My observation: There are very few model characters with big asses and hips, games with such characters can be counted on the fingers, which personally upsets me...
As it was rightly stated earlier "do everything for your own pleasure, without looking at someone else's opinion". Put aside doubts.., you like big asses, thighs, breasts, make your characters as you like. I am sure you will have your own consumer, your own connoisseur and your own fan. This is inevitable....
P.S.
It is not so important what kind of body your character has, it is important what kind of face. If don't like the character's face, the interest will be one-time and superficial. The face is a 75% success rate, the body is just a bonus.
