It's very much trial and error Arilynn .. and what you actually want. What looks good to you. I mean, that skin at Colona I assume the person who put it together thought it looked ok. My eyes thought ewww!
There's a fair margin for range with all skins but I'm agreeing with Charlemagne here that drawn skins are just that bit more pliable
But I'm not damning photorealistic.
