no structure...

i feel that the space hasn't been used correctly... i dislike the puffs of smoke coming out of its nose as they look odd and random, the framework doesn't look like it would move as it doesn't have enough depth, the random wires make no sense nor does the holes in the side of the head... now... your shading is whats keeping this whole thing together as such... your showing us that you know how to add depth and texture... iv seen your other work and feel that this is a poor example of what you can do...
