Well, you have the rights to the work you've made, yes. I will not argue that you have the copyright of the specific piece. The problem comes when you factor in that the work you have made is in fact fan art, based directly on illustrations and concepts that are copyright of Blizzard, which means that unless they have licensed it, you are in fact making a copyright infringement. I don't see how there would be any difference between making an illustration based on the IP in question and making a sculpt of it. But if you are willing to take the risk; knock yourself out! I won't stop you!



Oh and one more thing... Guh. Copyright laws... They're a pain in the arse to figure out sometimes.
