digital art newbie struggling

hey, i have been trying to learn blender for the past month, and i feel that although i have much to learn im doing not too badly. However, i purchased a bamboo pen graphics tablet the other day and intend to use it for gimp, sculpting and the bsurfaces add-on!which im interested in getting and learning. But i dont really have much artistic talent and have been struggling with using the tablet to create anything remotely decent! i have looked for many tutorials on digital painting and such but i really cant find much suited, can you please provide me links to resources that will help me get on my way with this stuff so i can start making better work? sorry that its not directly related to blender, but i felt this was the best place to ask.
