Forest's Guardian

No no, I wouldn't say the anatomy sucks at all. Actually, the anatomy is very good! I would say that the back isn't curved correctly though, as when sitting like that, the back curves opposite than what you're showing here, which is far more stiff and would make it difficult to lean over the leg as it is showing there. I made that mistake a lot, the back is a difficult thing to get curved correctly. I think the details are well done, but not taking away from the main part of the subject. I like that there's more to see as you look at it longer, such as seeing the snake and the different flowers, it's well put together and thought out, I think you did well there.
I do think you ought to look into more contrasting though, since there would be different light being cast in the background than in the foreground where the character is, and that would make the main character stand out more, even if you 'faded' the background, which can be done with a kneaded eraser (it'll 'lift' the lead coloring w/out having to erase)
Overall, I think you did well with this pencil work and I'm sure the more you work at it, the better you will become. Keep on plugging away!
