Damn, it looked huge till I saw the "*car not to scale"
But seriously, looks nice, get some wood stain on it. I also heard that if you want to temper it so it doesn't burn the wood as much you can put it into hot instant coffee, but check that first.
PS- Carve some stuff into it. Like Bible verses that prove weed is okay or real MJ facts, that's what I'd do. Make it personal.
