Well the EXIF looks good for this shot. It also looks fairly focused on my screen but it could use a sharpening. Check your AF setting to make sure the camera is focusing on the point you want. It could have focused on the bridge here. Maybe switch it to spot focus using the center focusing point on your camera, here you can download the manual.....
400ISO is a little high for a bright shot like this. Lowering your ISO to 200 or 100 will help reduce noise in the picture.
