So many colours. Holy damn.
I reduced what I could and unified the lightsource a little (which I picked arbitrarily from a random surface).
I also removed the crazy AA and added outlines to everything because some things had outlines and some things didn't and that was weird.
This isn't what you should do at all, btw. Just a few things you could look at. I actually prefer Friend's edit because it simplifies the surfaces, which is cool.
Damnit I couldn't stop myself. I edited Friend's edit.
Same story - different approach.
