Hey guys I was wondering if you could give me some feedback on this render.
Thanks 
Excellent! No criticisms from me - not very helpful haha. It reminds of the rat bikes in Road Rash (and presumably real life), cool concept.
Edit - googled “rat car”, seems like it is a thing after all! 
Get rid of the windshield and it generally needs to more rusty and rustic. Research “rat rods”.
Yeah give the windshield some dirt!
I just remember what we use to call these, doodlebugs. If you just look up “doodlebug” you get a lot of unrelated stuff, add “car” or “tractor” after “doodlebug” to some useful research sites.
