Not bad! Looks good. Is that an old Entertech water gun?! I loved those things. I may have even had that one.
Here's my 2 cents:
All of the silver bars & brackets near the trigger look sloppy. The grenade idea is creative - but wouldn't it be simpler to just have some C4? The bottom of the briefcase looks a little empty. Maybe you can throw some regular stuff in there for fun (toothbrush, stapler, a sandwich, etc).
Thanks for posting. Where are you located? Florida?
Yes we are located in Fort Lauderdale, Flordia. you know i thought the same thing about the briefcase, but the director wanted to be i guess different and use a grenade instead of C4.
