Awesome! I especially enjoy the floor, wall textures and the lighting used. It seems really "old school" in its texturing.
The only thing I could mention I would like to see if you could, and this is only a suggestion as what you have done is awesome, is see if there's a way to make the 3D runes that appear on the wall with the descriptions of everything appear a bit "sharper" in texture.
Above all, great job. I love it. Thank you so much for sharing with us.
