At your request Sukigod;
I'm in a lazy mood so I haven't repaied it or touched up the paint job at all. Above the muzzle there was a sculpted eagle (think like the hood ornament from a Rolls-Royce car) as well which really made it look quite special. All made with too much free time (kinda... also known as not sleeping between working!) and extruded polystyrene insulation sheets.
But wait, there's more;
Glowy! You can clearly see it in daylight, but my camera doesn't pick it up too well, so I had to turn the lights off. You even get light coming out of the heat vents around the muzzle. The torch I mutilated to achieve this even has a flashing mode, which I imagine is what happens when it is getting hot. Gets people's attention more too lol.
Compared to your Sluggas, its a bit rough to say the least. I think you are also taking a ton more care with your paintjob. That said, as yours are going to be prizes as opposed to a costume prop like mine, that is only right and proper.
