Aww, no steamies... o-o

Yeahhh, the joints should be easy enough to draw backwards; those can go both ways. Actually, yeah it'll be better to draw them backwards, so they'll be further away from angry runts, yeah... .p
Hmm, no steam pipes...

I'll probably still elaborate on the backside design. Add some kinda pressure compressor drum partly visible somewhere, and some heat exhaustion grills or something.
Hmm, I'll maybe also add the second pair of arms. Maknig it the huge construct instead of a large construct. It would better explain the design differences from... *rattle rattle rattle*, Galsic's (right person, right?) model.
Yeahh, but it's gonna take a while. @_@
