Looks pretty nice man! Great progress! But few things:
* move player a little bit downwards (so there won't be a visible gap between feet and ground f.e. in shadows);
* making player walk slower, cause he moves to fast for his walk animations;
* make damage (red screen) effect, less noticeable maybe.. decrease it's alpha;
* increase the speed of running animation (looks too slow for the running speed);
* change mouse pointers (crosshair while aiming, hand for items to pick up etc);
* make buildings translucent, if player is behind them;
* add some kind of a wind maybe, to make more atmosphere on the scene? Maybe dust etc;
* create a walking marker! when you press on ground (where player is supposed to walk to), create an arrow or so.

This is just my taste, and my two cents mate. All-in-all it looks great so far! Maybe I can get some more details on it later, anyway keep this up!

(was that a bug with shadows on 2:48)
