Some of your verts look out of whack, mainly on the window. They dont flow very well. Have you ever used the ffd modifier? I just found out about it a while ago, but when i model my cars its saved my life a hundred times :D
That octopus is gnarly, love it! I'm almost done blocking this in. I need to make a coil of hose, a sprayer and a few misc details, then probably push it around with some FFD.
I love, love, love this. Could you elaborate a bit what FFD modifier magic is involved ? Can be via PM, too :D Like someone said, it would fit right into tf2, and I'm heavily playing with the creation of a "space theme" where new rock assets would be golden !
