I'm replying a little late...but it looks like you ran into what I call an "Art Snob,"
DarthBobVilla. You'll find them in every field of art.  I'm a professional writer, and for many years, I hosted a writer's forum where similar arguments often arose, only the fight would be about literary work versus mass market writing.  Some writers feel that anything written for the mass market is certain crap--just as some artists feel that any artwork made with Poser is somehow inferior.  Such a critical conclusion just makes the snobs feel better about their own artistic efforts.  Ignore such people.  They're shallow and not worth knowing anyhow.  Do the type of artwork that you like to do; for art, above all things, is an expression of creativity.  :-)
