A really beautiful work! I like the way how you depicted this pose - nothing I could do somewhat decently in a million years, but you made this picture very awesomely! Nice combination of colours, and the quality of detail is also quite high - faved, this is a very great work indded! I really hope that you'll remember the one, who started the contest, and good luck participating!
I think the boobs are okay, they don't have to be supersize, 'cause it's just not realistic at all if they're always Double-D and even if Manga-Style doesn't have to do anything with realism, I also like the characters with flat chests instead of monster-boobs About the butt, maybe it could have been a bit bigger, but I think it's okay, that way^^
