sharpening your jump cut skills would be good, they're maybe a second out of sync, (like when you went to throw your laptop) if you had cut a few seconds or even a second earlier it would have made it easier to believe you had thrown it, aswell as the small pauses you leave before and after you cut to a new scene, jump cuts are supposed to leave no break, throwing you straight into the action.
Other than that I think your ideas are solid and you're obviously putting effort in.
