sweet

but how do you fit in?

the treads

look like the goliath tank from tht old battle tanks game.

Man

This is totally kicks ass, although as 'VideoGameDude' Said it would be better if you would finish it, can you finish it anyways?... This would look badass.

Short summery

The design is pretty well made, though the structure lacks technological sense as in why would a small miniscule sphere require large futuroso industrial tank treads?
The detail is quite impressive, but the polycount seems a bit too high in my perspective, though for artistic purposes that doesn't matter, but for video games it does.
Could use a backround of some sort but the black is better than the previous white you had, good call on that.
Render quality is superb, though a little refinement is needed for sharp sleek edges.
