How about just get all this out, do an original drawing not based of a photograph, to show people if you are either really drawing these pictures or not. Sorry about all the negativity your post has been getting
I can see why people think your drawings are photoshop. Maybe they are not used to your style of digital painting. I took a look through your older stuff, and though your style with pencil is a bit more rough, I can definitely tell that you have talent. Computer drawing programs are much easier to work with because they are easier to manipulate. I read in one of your comments you use Sketchbook Pro. It's an amazing digital painting program that looks like real paint if used properly. Even if you do trace every now and then in photoshop, it doesn't take away from the fact that you did go in and paint everything by hand and that takes more skill than drawing does, in my opinion. I trace sometimes too, not because I lack talent, but because I lack time.
