I like it, I think it has great potential, just unrefined. very fast pacing, but besides character descriptions, I feel lost while reading it. I don't really know where I am half the time. I feel like this could be better, and the pacing needs to slow down and focus on what's happening, we just started the book, and he's already killed a dragon. My overall advice is 1: Understand where you want the story to end and some major arcs you want to happen, and from there, fill the rest out. 2: As much effort as you put into describing the characters, you also need to put into everything else but dont get over bored and start describingevery little thing that happens, like if a guy had a nose bleed like 2 months ago we dont care, unless thats inportant to the story of course, but if its unrelated then we dont need to know about thay. 3: Make sure everything flows together nicely. oh, and just a tip. I'm not trying to be condescending here. Read what you're typing out loud, and if it doesn't sound right, then you need to rewrite it. that's all I have for you now, though.

I am utterly captivated by your book! It's a literary gem that warrants far more attention than it's currently receiving. The characters are intricately crafted, the plot is expertly woven, and the writing is nothing short of exceptional. It's a travesty that more readers haven't had the pleasure of immersing themselves in your work yet. I'm eager to help you devise a strategy to increase its visibility and garner the accolades it so rightly deserves. Let's collaborate to devise a plan that showcases your masterpiece to the world!"
