This is gorgeous. I can see what you mean by the shading, it does looks a bit off, but knowing you, you'll master it in no time. I love the glow on her nose and ears, her eyes are amazing. I really love how you've done the hair, it looks more realistic, or it does to me any ways. o.o' All in all, I'm very impressed. And I agree with Bri there - you made Photoshop yo bitch. xD
I feel like this is much smoother for you and not as shiny. Not that the shiny was bad D: because it wasnt! But this is a nice style to see coming from you, and I hope to see more of it. :3 and dont worry about how long it took...you will soon find ways to make it faster that you just didnt think of at first lolz X3 and even if you dont do anymore of this style, I'll still love your art work ;o lolz
Yous' be workin' that Photoshop. ; 3;
