I apologize for just jumping around and adding some of your concept art to my favorites without commenting, sir.
I'm surprised that I haven't seen this piece yet. Every other one seems to be floating around the internet among those who keep up with Frictional Games and Amnesia. It's such a striking piece. The colors stand out so starkly against the darker surroundings that it's almost entrancing to look at. I like all of the detail in the image, as well- the drooping chains, the thick bundles of cables, and even the delicate designs of the railings. Forgive me for gushing so much over this piece, but it's so very fascinating and marvelous! I can already imagine it's full effect in the game, and it is glorious.
