EXPLOSIONS in motion - Longarm's head

So I have a video game world idea (EXPLOSIONS) that I use as a vehicle for thinking about game design and visual design. For a while now, I've wanted to illustrate some scenes and aspects of the game, but then display them as little animations. So here we are - for practice, fun and hopefully some viewing pleasure.

I will add more and more tidbits of the world, building up this thing I call Explosions =)

 This is the head of our most common enemy, Longarm. It acts as a zippy little scout for the slow, lumbering Longarm robot - and once it knows where you are, it will quickly return to its body... unless you catch and stomp it into the dirt. BUT. Doing that won't  make the big bot too happy...
