no offence but you suck at irl building, to be blunt :P
Nowhere would i see as many weapons as that- like that irl. It just doesn't look irl at all either.
It kinda looks like you made a bad dsl wammer and added random weapons to it, take the wheelguards- they have sir k drills and a double sided tooth, tell me where you would find that irl, you're just abusing the stats of it to try and make a killer.
If i were you i would replace the wheelguards with something like a ski, have less bunched-together weapons and have maybe some BB and other weapons (full of spike strips on the wedge?) and make it flatter, it just looks ugly with that height :P. I don't have a problem with metal hinges aslong as it fits with the design (e.g. you need it like wammers, just don't make them sticking out too much).
Again, no offence but i am pointing out stuff that will (hopefully) make you a better builder, feel free to correct me.
