Grammarwise I found the first chapter the easiest to read. It was not completely free of mistakes but it was of a normal quality. After that it went downhill. I guess you speak a Slavic language or another language without articles? Either you need to read up on articles, or you need a beta who speaks a language with articles. The possessive 's could use a bit of work too.
Storywise the chapters are a bit short, certainly the first ones, and some things would have been better if they'd been a bit more worked out.
For me, the Sixskins-Harry part stands out, negatively. Now it's a quite useless part of the story (while being more than half of the story so far). Other than eventually teaching Harry changing, nothing interesting or necessary happens. We learn a bit about the Harry of this story, but three chapters for this? And for a big part about a character that I assume is useless for the rest of the story? (That's not to say he can't be used, but combining his part into one chapter would already help. And if you could let it make more sense and flesh it out, that would be even better.)
And depending on how Harry arrived in the GoT world, even the changing lesson is useless. But I guess from the hint that he was enslaved, that he didn't live through those 2000 years while honing his skills but inexplicably not learning changing? If he did, he's even more useless than canon. How did he even keep his wand then, or is it selfmade or otherwise not his original?
Anyway, the story jumps a bit too much with too little meat on the bones of the chapters, and I'm left with too many questions. Why did Harry even kill the animals? Why didn't he catch Sixskins lying when he said he hadn't taken over a human yet, while Harry completely saw through him when they met?
The story has potential, even like it is now, but most of it is squandered. The story telling is mostly good, though article-less and short and sometimes a bit confusing in the dialogs, for example, in the Harry-Mance dialog.
Oh, and if it's possible perhaps you could correct the warnings? I didn't see any "graphic sexual content" in the first chapter.
Author's response
I am unfortunately from part of world where speaking English is frowned upon. I have taught myself because of the obvious reasons. So my grammer teacher are some boring books. I admit that sixskin part is useless but that was first thing I ever wrote in English, I couldn't not publish it. Warning is to intice the cirtain type of readers :-). Thank you for your review. Hopefully I will get a good beta who can save this story grammatically. Dont worry about plot, I will not disappoint any reader. All things will become clear such as wtf is harry doing up north, when he came to this world, why learn skinchanging, how much magic can he do, is his wooden stick functional, why is he playing the game of thrones. Perhaps you can help me find a beta who is ready clean my dirty grammar.
And when did harry kill the animals? sixskins is paranoid bastard to assume that.
