There are so many choices on the net. I am overwhelmed by them. So far I just find eye candy texture particularly useful.  Besides eye candy , 3d.sk and the items in the marketplace here,  what do you think is  useful for textures of characters? I usually make human skins, hair and clothes.

Btw,what would you suggest for learning to draw textures for 3D characters? Is there any free online resource? Or good book?
