I'd have used the 'distort' or 'perspective' tools in PS to correct the leaning verticals on the right. Sky is a bit washed out... a little less exposure would have helped, you could have rescued the shadow detail using curves in PS. Shot is lacking a 'wow' factor for me.
even though the clock tower is in the center of the composition it looks very odd there so far away from me, the spectator... It looks as if the parc and the trees are the main subjects of interest and then suddenly there is that tower! The effect is, mentioned already, odd and I don't realy like it..but on the other hand you score some points for making creative use of the centered composition by overruling all rules about it!!
Good use of leading lines. Tower looks like it's leaning slightly. I think this would work better if it were more tightly cropped - the sky is fairly hazy and blah, so the less of it in the picture the better. And perhaps a polarizing filter to darken the sky as well.
