Welcome to Gaia! ::

You drew all this just with a mouse? Impressive. Personally it looks quite alright to me. Ditto what others think.

Very very impressive lines with a mouse! biggrin I wouldn't even attempt lines with solely a mouse and I don't have any patience for the pen tool. XD

The only things that stuck out to me were the need for more folds around areas of stressed fabric, as said before, and the girls hair iswhere the top right is very blank. But you may like it that way, right? smile
Very nice!

Wow, a mouse? Christ, you have a lot of patience. This is fantastic for using no tablet. I would flip a table if I lost mine. D:

The guy definitely has to lean forward more. o: The girl would have to be really light or he'd have to be super strong to carry her like that. It's a lot of stress on the back muscles to be almost completely upright with so much weight behind him. The girl's farthest leg should also be lifted a little, after all she's in midair. I also recommend having the girl lean backward a little, since her back is against his. If he's leaning forward, it seems to make more sense for her to lean back.

I hope I didn't sound too redundant. I really like your anatomy, the legs and hands look nice, as well as the bends at the knees if you know what I'm saying. There's a good amount of folds in the clothes, and I'm not gonna repeat what the others said about needing more. XD

Fantastic job!
