I like this but I think a shotgun would have more of a solid stock and the front grip may be done differently. The rest seems really nice.
The stock would need to be a pair of wires to set up a flat plane against the shoulder. But otherwise, pretty interesting
looks cool actually but maybe a standard front grip (like a pump shotty) would look better? basically yeah looks awesome, specially with the top down cartridge thing but, how bout making it a pump shotty? edit: just realized that i was referring to one of the pics in your photobucket page, the one where the shells are vertical on top instead of horizontal, use that one
I would love a first person view! However, I have no doubt that this will look splendid in first person, thanks to the luger-type mechanism it will be also fun to watch (just hard to animate) :D Great concept! Just needs a more solid stock!
The support which goes against your shoulder should really be bigger otherwise you'll eventually get painful bruises.
