Nice! Has potential.
Two tips:
1) When having different lighting conditions on screen at the same time (0:07), and if you can change EV, expose for the sky, and use some other kind of light (reflectors, lamps, etc.) to highlight the talent.
2) @0:23, which I guess it's the same scene, the gun shines, which is a dead giveaway of it being plastic, and fake. Spraypaint it with some matte black. Guns, if not made of metal are mostly made of matte materials.
