main complaints:
spinny dials are irritating to use. The sliders of the original creator were much easier to use.
Takes too long to render images, meaning you can't quickly flip through options to experiment, it takes hours to find one you like.
Not enough options, on anything, at all. No skin colour options, no visors, not enough funky hair colours, not enough hairstyles (maybe keep current styles but allow hair sculpting? not enough clothing options
not enough differentiation between bloodlines, they all look rather similar.
Sculpting is a pain in the ass, you can't tell what changing things will do or how they can be moved, also there are gaps where you should be able to sculpt, the biggest issue is between the chin and the jawbone, there should be something to move, because as it stands, there's this unnatural looking hole there unless you're very very very careful with it, you get that weird sunken Michael Jackson look.
No option to make characters blind
lame backgrounds are lame, the old ones were better then this, just give us those.
Not enough lighting options.
I know its a work in progress but overall I'm thoroughly unimpressed at this point.
