I need feedback to know whether I'm doing things right or wrong. But when there's no response at all, you start to wonder if you should keep going.
In that case, let's start with your synopsis. And, incidentally, the more I look at your cover, the more I get annoyed that the typography is so far up, because it wastes potential. And the author is also missing, making it an image with a motivational quote on it, for all we know. A cover belongs to a book; a book has an author. This looks as if you're ashamed of being associated with your work.

Anywhoms, back to the blurb text:
Vinter is a man who lives to repay a single debt. It is not a financial obligation nor a pledge of loyalty to a king. It is a blood debt that arose on the night his world burned, leaving before his eyes only the cold reflection of silver armor that took everything from him.
Technically, I don't think this mysterious approach is bad at all, but it's getting so much, that I'm wondering if his enemy is a sentient piece of armor.
A former soldier, accustomed to dirt and iron, he spends years searching for a ghost from the past.
"As a" would fit better, because you introduce a character - "A former soldier" - then you state his context - with dirt and iron - and then you change into a descriptive narration. Take out that half-sentence, and it becomes "A former soldier, he spends". Compared to the very profound was of speaking before, the very ordinary rest of the sentence, starting with "he spends," kind of feels out of place. I can't properly put my finger on it, but it just sounds off.
"As a former soldier, hardened by dirt and iron, he searched the land for many years, shackled by his thirst for vengeance" - maybe something along those lines would be more fitting? Not perfect, sure, but anyway.
His enemy is a long-eared creature that considers itself refined and untouchable. In this confrontation, there is no room for nobility, only for the scorched emptiness inside and the sharp blade in hand.
So... his enemy is an elf? It just feels like we're playing the pronoun game. It also feels odd, from this mystically-sounding generic text, we suddenly skip to a wanted poster description of what target to lock on to.
"His enemy is a
long-eared creature that considers itself refined and untouchable. In this confrontation, there is no room for
noble virtues;
nobility, only for the scorched emptiness inside
of him and the sharp blade in
his hand
s."
I also personalized it, because the scorched emptiness already feels "edgy", and it's definitely something personal to the protagonist, so it should read like it as well. Also, big blades aren't properly held in one hand.

"the sharp edge of his blade" or "the sharpness of his blade" would likely do as well.
Intrigues whirl around him, yet even someone like him has those who support his broken soul.
Now I wonder where intrigues even come into play, because your words up to this point paint a picture of a lone warrior traveling to find traces of some mythical being, like the father of Sam and Dean Winchester. If it's someone known to anyone at all, why would it take years for him to look for that guy? Anyway, it's your story, so I'm going off of what I'm seeing. The sentence itself is a bit convoluted and the intrigues come out of nowhere, so you have to take the edge off.
"Yet as he finally succeeds, he has to realize that all is not what it seems, and Vinter has to hold onto his newly found comrades, in order to brave the storm of truths and lies ahead of him."
Winter knows: when he finally meets the one he seeks, the price of revenge will no longer matter to him, and the thirst for killing will drive him to the very end. But for someone who has already lost everything, a silver debt is the last thing that keeps him in this world.
You misspelled your MCs name, which is not a good look. Also, at this point, you just switch into telling us things in detail, which - here as well - doesn't fit the rest. In the last sentence, it also feels like you just want to add that title somehow, but it rings empty - those are just words. They mean nothing. What the hell is a silver debt? Instead, take something like that sentence I put together one spot above and add onto it:
"[...] knowing the price for revenge might be everything. As a man, hardened by steel and iron, having nothing but a single debt left to his name, he shall fear not even hell beyond his death." - I played around with the fact that his life ending is just nothing special at this point. Maybe it will give you ideas.
Anyway. Why did I drag this out so much? Because after clicking on your story, based on the cover and title, a reader will see your synopsis, tags, and content marks, which will give them insight into your story, so they can decide whether they wish to proceed or read one of the other countless books on this site. And your synopsis wasn't really great. It sounds generic - which is fine, when you're looking for something like this - but at the same time, a bit muddled. Like, what's the world we are set in? Did the world end, or just a city or village? Who's the enemy in a larger picture? Is it a monster? An emperor? How does a guy like the one you describe even find people who are turning into close comrades to be by his side? And does he care if THEY die?
Ponder these questions - maybe it will make you revise your synopsis or even think about the story at hand, which I haven't yet looked at. Or maybe don't change anything at all - in the end, I'm just spit-balling here.

EDIT: Also, maybe you should add numbers to your chapter titles - it's just confusing in the long run, when stories just don't do this.
