Gimme dat stock. As for the sig, incredible as usual, really good work, except for the thing to the left of his/her helmet, it looks a bit out of place. Well done though. Maybe try to make the bisor more the focal and have all the action leading up to that point.
Kind of wide, but this sig pulls that off nicely. Over all it looks great, though not your best it's certainly in the top. That one effect to the immediate left of the spartans helmet is a tad distracting though, but that's just my opinion.
