Steam/Electro Driven Deer

Hullo friends, first post for me on Blenderartists (yay!)
This is one of my more advanced projects i started on a week or so ago, and, while I still need to figure out how to do the legs, this is a basic composite render of it so far (i’m still relatively new so some of the composite nodework is a bit iffy right now). He’s also missing legs and neck, but i’ll get to those at one point
I can’t seem to decide whether it would be better to make him steam or electric driven, or what sort of environment to place him in (city, industrial, natural etc)

Any suggestions would be greatly appreciated

looks great so far. welcome to BA.
