(u3u I just decided I liked the style and it was so much easier than anime...that shit gets complex. and with this pic I used a reference picture. I do that a lot. I use pictures that I find and use the basic shape. (not tracing usually) and I just try and re create what I see then modify it to make it look like something I would do then add color and blah blah blah. )
Have you tried doing it by hand? it looks anime-ish to me. Now im not one to judge mind you im a hobbiest at best but it looks like you had a hard time with the computer. Try sketching an outline then tracing over it then adding color but do the original in pencil. Belive me I have a tablet and I once in a while turn out somrthing im super proud of its just not as personal as good ol fashioned pen and paper.
