Female: The base texture should either be no-makeup or very naturalistic makeup. Textures which only come with heavy makeup on the face are frustrating. They disallow versatility. Having 3-5 makeup options can be nice, but because makeup can be applied by mixing textures or blending in a paint app, the most important thing is a relatively plain base. Nails? Don't care. Easy to color in the Materials Editor or to paint in Photoshop if need be. Male: I agree about "too many goatees," even though I think they look good on a guy. If you have a good beard product (esp. DAZ' MilBeard) you can always add that yourself. Again, the main texture should be relatively plain. Eyes: Unless the texture artist is confident that their eyes are of very high quality, I don't care about having several color options. I tend to use my favorite eyes (from textures by StefyZZ, Mint, and quim2001) on all my characters, rather than the undetailed ones that come with some otherwise fine textures. I also agree with what Crescent said about ethnic diversity. That goes for morphs as well as textures. I'm happy with good African textures I have, but would also like to see more good Asian and Latino/a textures.
