Heya, it's fine to use as an avatar! It's just that I believe the general preference is to wait until a piece is complete before it goes through. If you had not said that it was still a WIP, I don't know what would have happened, I don't decide what gets approved or not! As it is, it looks good to me, but I'm sure the whole thing will be better :)
I realize that when I say "work in progress" it makes it sound like this on its own is not a full piece, but right now I'm using it (as is) as my avatar and I'm actually using it on facebook as well as my profile picture. If I had not said "The full dragon is still a work in progress" would this have been fine?
Fair enough. :) I'll keep at it - I was just curious. Hopefully I'll get something up at some point!
