Partly twitchy, but I guess that's what happens when you have an assault rifle in your hands. To be honest, I'd be nervous too if I were tori.
Anyway, I loved your beginning where you ran to cover behind the boxes. Same thing with the way you got out from behind them, and ran to the next ones. Nice fluid movements, that seemed realistic for the environment. I will say, Uke moved really strangely in this. You should have worked a little more on him. The way you stepped up to the "gunshot" was nice. I loved how easily you marched up the stairs, the fact that you actually turned around to "check" and see if there were any hostiles impressed me. I think many people would just march up the stairs and go.
Very realistic, albeit a little twitchy. Great job with those stairs.
