He does look very sexy indeed. X3 I love his expression and I really adore the way you drew his belly, I think the lines underneath the belly and in his groin area look very nice (*slaps perverts*), and it looks like you drew his outfit pretty well, too--I especially like how the buckle is hanging down like that. Also, the bellybutton was a nice touch, I love those things. :3

Now onto some other things: I saw you requested a critique, so I looked around for things that looked critiqueable and the first thing I noticed was Scourge's eyes. His left eye (not ours, his) looks fine, but his other one doesnt seem to follow it and to me it sort of looks like it's gazing off in another direction. Another thing are his ears--the ears themselves are drawn well, but they look like they need to be scooted back a bit to be more aligned with the corner of his eye. The quills are alright, as are the muzzle and toothy grin (Gotta love that about Scourge, ne? ), and the hands look pretty okay to me too.

Overall this is a very nice picture, it's been a while since anyone I'm watching has submit Scourge fanart, and as a matter of fact I think this is the first Scourge mpreg pic I've ever seen. Nice job, I like it a lot, and keep up the good work! X3
