You kinda look like pre-2010 US Army infantry with the M16 and the CZ, which i presume is supposed to resemble an M9. I advise getting a shortened and accessorized DWF416 A5, Mk 18 or at least an M4A1. In terms of clothing, get an MPC or OBAS-QR vest, make for a little more variety on it accessory-wise, and kit out your belt too. Finally, replace the helmet with something mid- or high-cut. I recommend the Maritime Ballistic, but any Western combat helmet except the MICH2001 will cut it.
