Christmas!!! Now I can't un-see it!
Pretty awesome. Animation is lacking, but I always say that about simple "bobbing". Red and green lights seem to evoke christmas or roses, for me. I'd try to improve the grey ramp with a bit of color infused into shadows, at least, and change those green lights to a different color.
I love those red eyes. I've been trying to figure out how to make eyes like that for a while (like the sentinels from the matrix). You make it look easy -_-'
