I know its noobish but...

You should read some tuts..nothing makes sense in this sig. The first thing that comes to mind when I think of sonic certainly isn't assault rifles. The triple focals is really awkward..and it looks like you took a premade sig and just duplicated it a couple times, scaled it in all jacked up diameters and just plopped it in random areas.

also da AK looks sooo out of place base on da colors
