I checked out your build, it was a big help in answering some questions! I've got my build up on the UK garrison but I'll post some stuff here too.
I filed the teeth away, still need to do some more, I was a bit conservative at first. I haven't trimmed the bottom of the lid, was going to do that after it gets riveted together. I'm a bit concerned about the fit, but hopefully when it's all attached it will pull the ears in without popping the brow out too much.
Also work on the blaster has continued, nearly calling it done, just needs dirtying up and finding some decals/printout for the scope lens, as I lost the one supplied with the resin kit. Doh!
