This is just the Scorpion Orb Launcher with a different mini-fig (http://www.peeron.com/inv/sets/4774-1). Even if you changed a few things here and there, that doesn't make it your own creation. At best, this is a modification, a very basic, uninspired one at that.
Even cooler! The cockpit with the 2 opening sides is a great system, and that tail is....impressive! Moreover, the choice of colors is perfect! I hope to see some others crawling awesome insects on your homepage :D
