The vista is better but how about some vegetation. Maybe some dead logs in the water below.
I had a run around and i really like it. Weapon placement is good. Flow is easy going. I like the openness. AR2 alt fire isn't vary effective in this map, so if you like, don't be afraid to add some more.
There was one bad thing that really stuck out though. The wooden floors were far to reflective. Beat up, dirty, wood plank floors don't reflect crap. Everywhere i went i could see a reflection of the sky box on the floor.
I assume its time for nit picking...

The air is far to clear for the light spot to stand out so much. I'm not expecting you to change it but i think if be cool if it was a little misty in there.

I don't know how this works but it looks like the 2 sections that im aiming at are flowing in the opposite direction. and think it would look better if the water flowing over the rocks was moving slower than the main stream.

Spawns so it looks like its floating.

Wires need slack.

The shadow on this box are to dark. (pitch black)

I normally wouldn't point out something so trivial but it just stuck out for me. The wood hear is way to clean. Maybe add a overlay of some debre or something.

This rock is casting a odd shadow.
I hope this helps. Any idea on when you could have a final?
