I kinda like it with the blue marker eyes.
Get yourself some permanent Sharpee markers, and hit that eye with the blue again.
then take a lighter, and carefully melt the surface of the eye. It will seal in the marker, and will last longer than the bait will (hopefully it will get chewed up quickly).
When you do not hit with a flame, the Sharpee will do one of two things, or both:
rub off easily, or keep leaching into the bait until you can not longer see the color.
Try hitting the eyes first with a silver Sharpee, then hit with the royal blue Sharpee, then hit with the flame.
Give it a shot before you buy paints--there are several that work fine, but none that look that realistic for eyes, IMO.

Your forgot to photoshop out that "secret" pink block of C4 in the background.
