Hi, I'd have to say it looks pretty darn good so far. Is this a 1/35 scale model? Did you wrap the barrel there with tissue or something similar? I know years and years ago Tamiya had out a 1/25 scale Chieftain kit, but I think this was back in the '70s. Sure would like to see them re-release that particular kit again some day. Is this kit one you picked up just lately? If so I'll have to check into one. I seem to have developed something of a 'thing' modern armor, at least post W.W.II stuff here lately. Yeah, like I'm not backed up enough as it is, I have to up and go into another era. Ha!
Good luck and take care, Sgirty
