Don't let it get you down, alot of folks can only make themselves feel big by trying to make someone else feel small.  And anybody who thinks that "anybody can do them" or that it does not take skill to create 3D art, I'd disagree with strongly and I've worked in several artistic mediums.  Their are incredible things that can be done with 3D art and animation, and I've seen a great deal of creativity with it.   But like any art form it takes time, skill, and vision.  That's true in any art form.

Creativity and expression are our birthrights, and I hope you will continue to use yours.  ^^
