Is this thread intended to enliven the international section ? :P
Actually I also have to agree with Darth Bane & soulforged (I'm so predictable).
Apart from Star Wars, I especially like Yukirin's pictures (although they are not necessarily 'erotic', but really well drawn and perfectly suited as wallpapers...)
hmm...this is a tough question. i love Royo and Manara, but there are plenty of Japanese artists i also like obviously. Masamune Shirow is one of my favorite artists period, and he happens to do erotic and non-erotic.
