I like it too, but I'd make a few changes, having been a PMC in Iraq since 2004....
I'd ditch the knife in the rig, as those who carried it got ripped for the "rambo" look , and it served no purpose other than to look good in photo's, and your mates would slag you to bits for having one....
The M4 CQBR is very well done, but the PEQ isn't normally carried , and a suppressor is again something that wasn't commonly seen out on the ground, that's not to say there were none, as I knew a few blokes who had their own "cans"..
I like the sculpt, it has character, I think you could sell this commercially....
I'd be interested in getting a 120mm sculpt of myself done, if there's anyone out there willing to undertake a commission....I have a picture of myself that I'd like to see in a sculpture....
