Hi since im bored im gonna write alot of stuff here
The hummer :
The dimensions seem wrong. The roof is very tall, and should be lowered quite a bit to make it seem more compact and sturdy like the real humvee. Right now it looks like a SUV :G
Ump looks neat.
The MP5 looks way too defined, if you know what I mean. The cuts into it seem to deep.
Shotgun looks trippy, don't know how to explain it. It doesnt look "real"
And that last pistol, wasnt that just featured in some sort of "learn 3dsmax" tutorial
