I've taken my rough draft PNGs, spiffed them up a bit and created a "revised" icon. Same look, slightly different colors and little tweaks. Attached is a zip file with the *.icns file in it. That file has itself as an icon.
I made the little guy's blue more saturated, darkened his eyes to stand out more, and gave him bright red shoes and ball. I shrank his antennae so he could fill out more of the icon's area. Also made typewriter lighter and a cooler hue to help it recede. Smaller icon sizes are tweaked to look as best they can. Its not much of an improvement, but it helps it pop a little bit more on the dock.
Hope this helps.
