The shading is amazing.... Coloring is, too. <333 You own at colored pencils.... Especially on the symbols. :D Good job on the hands and the mask, and the green makes it very eye catching. You basically did everything right. xP

I love these colors, effective use of complementary colors, I would say ;D
Fantastic fur texture around the neck, and I adore those toes.
I would be careful about how you do the tops of feet/paws, those can be a bit tricky.

First of all, thank you for such lovely comments! :) Regarding tops of feet & paws, do you mean drawing them or coloring them or shading them...?

I think your could benefit a lot from studying the anatomy of paws/feet, that is, drawing them.

I would look at http://goldenwolf.deviantart.com/ 's art.

Ah, yes. Thank you. Usually I draw too big so I've never had to draw feet before, much less canine-like feet. Thank you for the advice!
