Maybe he/she just wanted to draw a genderswap version, period. Only then applying whatever look/outfit he/she wanted to give the character. Same goes for the other genderswap pic you just commented on (fav.me/da31fqs
). If you ask me, going from picture to picture just to state how you're upset with how an artist wishes to draw a male or female rump, without even offering any further feedback on the rest of the picture, sort of makes you look like a jerk.
I'm not saying that what YOU, personally, wish to see/find is bad or an unreasonable desire. But I don't think you should use it as an excuse to just go around randomly interrogating people who just wish to draw a harmless piece of art in a manner THEY desire.
I suppose though, to give you the benefit of the doubt, I also have to ask - What do you truly hope to accomplish, by posting such comments, so randomly, on assorted pieces of art?
