Don't worry about what other people think, just create art. Don't let other's put you in a mold (that is what my daddy always tells me). So what; you use Poser, Bryce, your scanner, Photoshop, a little pencil or paint here and there. It doesn't matter, you are creating art for you and you alone (even if it's for business, it's still your art), the people who happen to view the art is only there for the ride. People don't care how you got to A then B, they just want C the end result. I was just reading that in 3D World and it really hit home. You don't have to explain every little thing you do, your art will speak for you. It's not even how much you produce, you can have 1-3 superb pieces versus 40 mediocre stuff. All people care about is if you have the talent to wow them. If you have the talent you will go far, everyone notices talent even in the humbliest of artist.

Like all technology, it will take a while for others to see digital art as art, but it will come. Just hang in there.
