I like what you did to the AK, bigger is always better, right? I'd go a little less shading on the grey handle on the bottom though, just a little ;) sniper is good, nutcracker is good. There's already cake-on-head hats on era. So, if you still want to make one I'd say do a cake that's even more different from the ones we already have. And I like the hat, but I still think it'd make an even more awesome head =D
