I was browsing DA, downloading some outfits and I fell on this fantastic model. I really want to try and duplicate her body, do you guys have any advice on where to start?
I've tried using the standard morphs, but it's too extreme I guess and there are so many options. I don't really make custom characters so I don't know where to start so any input is more than welcome.
I'm mainly interested on the midriff part and the arms, the breasts are not that important.
