Nice shot. I do agree with cropping it. It is one of those 50/50 mistakes with the horizon dead center in the shot. I think the building are in good focus but I can't tell with the size image here. Overall for an in the moment shot good job. That's one of the most important things is just having an eye for a scene even if you can't capture it that is the easy part learning how to control the camera but envisioning the shot is important.
