Excellent
Anyone that says that this piece "sucks" or "aww man God AND furries! You suXXor!" is a shallow idiot. If you can't look past your own issues, you shouldn't critique someone elses work because you can't do it fairly.
Anyway, the drawings and style are, needless to say, breath taking. Of course I can't be sure, but I think the sketchyness was intentional, that was the style that the artist wanted. I think that the grays, as opposed to fully colored, set the sort of melancholy mood that the piece is supposed to have. I appreciate that you've shared this with us and I hope that you ignore the ignorance of some people and continue to create beautiful artwork.
