Presentation is job #1. The photos of your work display a considerable lack of care. Acceptable photos should center the art both vertically and horizontally, and the photo should be cropped so that ONLY the art is visible. Also, several pieces are shot at such a low resolution that they are virtually useless as prints. There are many tips on this site and elsewhere on the web for shooting artwork. You are competing with tens of thousands of artists on FAA, let alone the rest of the art world. Don't shoot yourself in the foot. God helps those who help themselves.
