I would like to see this place during daylight or at dusk and in color - this photo isn't showing me enough detail. Lovely choice of subject for the challenge, though!
Good centered compisiton. I think you could have croped this shot a bit tighter. I like the way the light is coming out of the windows around the base.
Well exposed, and there's good detail, and a good capture of the light. I find the composition very weak however - so centred, so much negative space, so little else to guide the eye, and all of that with a quite 'ordinary' seeming viewpoint - sure, it could be the most difficult view to get at in the world, but we don't know that. You need, I feel, and especially with such architectural shots, to add some element of difference, or of the spectacular, of of the location. the building is interesting - that doesn't automatically make the photograph interesting.
The exposure on this seems overly dark to me, with little contrast.. Also, the building seems to me be leaning or sinking. Lastly, I would have probably cropped it a little closer, especially on the right side.
