It's "ok". The subject may be a bit bland. Nothing personal, just an observation. It's hard to crop a shot like this without seeing the perspective distortions (curved lines). Good luck in the challenge.
mmm the yellow could be acceptable, the true problem of this image is geometrical distortion that you cannot correct in basic editing. Since the composition of this photo is based on the building simmetry this circumstance is a distracting 5.
nice subject for this challenge but if it were possible to maybe not include the trees at the bottom of the frame. It would simply the image more because they really don't have a part to play in this shot.
