Warthog/Halo model

Modeled after the Warthog from the PC game Halo. named Warthawg for me because i dont want any sueing of me going on. It seems that what i have in mind for an object i model never seems to get pulled in the right direction, so, this is technically a “work in progress”.

Well, you have the basic shape down… but far to blocky.
What is this to be used for?
