Brian, I really like the image. Neat looking caterpillar. The only thing that bothers me is the colored border, I find it a little distracting.
Brian,
Can I suggest plain white for the borders, I think you will find it makes a big difference? There is a free download called 'FastStone' image viewer that has a selection of borders of the drop shadow effect that you can adjust if not availabe on your software.
