Construction Vessel

I found time last night to finish this construction vessel concept.  I've been pretty obsessed with construction vehicles lately.  I think it would be a really cool piece to see a science fiction construction site with vaguely familiar yellow and orange construction colors, cones and vehicles but really push them 70% more into science fiction with droid construction workers and such.  I'll decide after the bulldozer model if I want to work on this guy next, or the Nasa robot.
