Not much you can do about the converging verticals now without making it look even more distorted, best you can do in future (apart from using a tilt-shift lens) is keep the camera level and not pointed up, and move back more to get it all in if you can. Either that or a multi-shot panorama. An ultra-wide is always going to exaggerate the perspective, even more so when pointed upwards slightly.
It does seem a bit soft and out of focus, maybe down to the processing though. I'd have also taken a couple more lower exposures to get a good clock face to paste in place of the blown out one.
