Have you tried looking into destoyed building pictures from Syria? That might help with what bullet and explosion damage looks like against concrete structures.
Yeah there's way more damage going to be done to him! it's just a start, plus im keeping in mind what is visible once he's placed inside the dreadnought
Looks amazing! Love this! You lost the mood of the concept piece though, but you could tweak with lighting and a few more damaged props. Mess up that floor.
Dig around in videohelp.com they have a ton of tools listed. Usually with video files the header contains important info, like kitty says... if that's damaged the rest is a mess.
