Great view of the Houses Of Parliament. Feels like you have cropped it just a little tightly on the left hand side though and I'm not a fan of the large black borders on the top and bottom of the shot.
The problem with shooting a scene we have all seen before (as you must for this challenge) is you can't help but compare the image before you with those in memory. This is a nice shot but for a few flaws, the blown out face of the clock tower, and the unlit portion of the building, both tough to deal with given constrains of shooting dates and limits on editing, but the strong yellow cast is not a choice that serves the image well. Did you choose this or forget to put it into sRGB before saving to web?
There is only one thing wrong with this and it's the clock face - the white dot just doesn't work with the rest of the image. Also, the dark area on the right of the building doesn't help the overall postitive effort. The font is good, but the color should have contrasted less with the overall gold tone of the image.
