I need to look at these on the big screen tomorrow, but from what I'm lookin at right now, this rocks!!
The is indeed a RM Prime head (that includes the KO oversized one as well). Like others have stated, it's cool but it looks alot like Onslaught.
Awesome work man!!! You gotta paint this ASAP! I'd be a fan of Ultra Magnus if he looked something like that!
Damn, I was just going to use Searchlight's head on WFC Prime and paint it.... This DEFINITELY beats what I was going to do!
That is awesome. Love the guns, the fact that he looks like he's gonna kick Deceptibutt, and that his alt mode is just amazing.
