Let's just drop it. The skill level of the person that is giving criticism shouldn't determine whether they have the right to voice their opinion on a piece of art or not. If you got a comment from someone that you don't deem knowledgeable enough to be taken seriously or just stupid, then just ignore it, but don't let it escalate into a flame war or pointless "See, I'm a much better artist than you! Owned!" thing, even if you and many other people honestly think you are indeed much more skilled than the OP. If you're really such a good artist, then have the decency to somewhat keep that to yourself when you're not showing artwork. Not aimed at one of you guys specifically. EDIT: Oh, and @the OP, don't put "Open to all comments" in your title when you obviously aren't.
