Details are important to me too as I do large and often close-up renders. Without enough detail that doesn't work too well. Like Laurie said - feet! GND-Ana has the best feet around, they actually look like feet and you can point them without them turning into ugly balloons! V4's feet are an embarassment.

Clothing - yes, I go for fantasy/scifi stuff mainly. Everyday stuff isn't very useful to me and simple dynamic clothing I can make anyway so I never buy that. Detailed and interesting conforming clothing like Uzilite's scifi gear, Parrotdolphin's fantasy clothes and some of Xurge's fantasy and scifi stuff is the type of thing I go for.
