Technical: Well focused and centralized. Effects have been used to increase the effects of the night sky and the building's lights help increase the drama of the photo.
Composition: The main subject, the cathedral is centrally placed with the dramatic sky emphasising the features of the uplit facia of the building. The fountain in the foreground detracts from the image by drawing the eye to the left bottom corner. Although the TV tower is a landmark, it looks out of place and the distortion of lens makes it appear to be toppling towards the cathedral. The lower right corner appears dark and featureless.
Overall: This is stunning picture of a fine building. The use of effects has made for a dramatic image which is close to being over manipulated. The TV tower, although a landmark, and the fountain detract from the main subject. This photo certainly meets the challenge for Architecture, but falls short of displaying just how fine the building is by being too all encompassing. I would love to have seen the main arch at the front shown in the same lighting, but closer. A very good photo that many would be pleased to have taken. The marks it got place it where it should be in the challenge and I hope you go on to take more photos of this subject. Thanks for allowing me to critique this shot.
My very first impression was 'dramatic'. The second was, however, 'too much'. I like be POV and the way you chose the time of the day to shoot, but I find the contrast a bit over my taste. Composition-wise: the fountain could be left out if shot from a bit to the right.
