Legion scene from Tomorrow's Dawn - Chapter 5

I've decided to make a scene from the book in SFM and it turned out pretty well. Scene takes place right after Shepard, Zaeed and Jacob dissapeared in the wreckage of the dome.
Scene and environment slightly different from the book, but I've done the best I could with SFM tools and addons and that's how I see this.

Map and scene were built by me.
I do not own any of these materials and models:

Mass Effect characters, models and universe belongs to BIOWARE;
Background textures, dome models and background cliff models belongs to VALVE, as well as SFM;
Tomorrow's Dawn book by ElectricZ

Addons were used:

[Mass Effect - Legion Playermodel] for Garry's Mod by Vipes
[Mass Effect: Turian Defences] for Garry's Mod by Kali
[Mass Effect: Weapons PROPS] for Garry's Mod by Kali and Wasp
