Assorted Images/Designs for Jewelry

Here is an assortment of small images I'm working on for potential use on earrings, key chains, pendants, etc. These are in the neighborhood of 4 by 2.5 inches. Their names are, starting upper right and moving counter-clock-wise, Complementary Bird, Post-Modern Bird and Handheld Portrait. The 'Zoom' pic is Surveillance Bird. ;) It is slightly larger than the others. I used primarily felt-tip on these with some gel pen and color pencil. Original Jones Art. PS: Input from my trusted artist friends will be appreciated.
