Okay, time for some comments.
1) Arthium was good. Very good.
2) I like the ideas behind some. I emphasise ideas unforntunatly though.
3) You really need to work on tails. They change width constantly as you go along.
4) You're weakness is Pokemon. If you're really stuck, buy the FR/LG stratergy guide, it has the Sugimori art for the first 251 Pokemon, so can help you with proportions and details.
5) XD001 looks like a mildly annoyed normal Lugia. The main problem was you didn't change the head ornament, XD001's are far more sinister and blade like the Lugia's.
But yeah, you hand draw much better than I did just over half a year ago, keep practising, as you have, and you'll improve greatly. All I can say is if you're stuck with proportions, get reference material of what you want to draw and then practise drawing shown poses, like Sugimori art for Pokemon. It helps a lot. I improved my anime style art in about two months by doing that.
And frankly your computer art is better than anythng I could hope to do.
Did I mention that Arthium was good?
