I would definitely level this, the tilt is distracting. Try bracketing your exposer and then pick the best, this is tough to expose with a digital cam because of the bright sky.
Nice reflection, pity the sky wasnt a bit more interesting. Also I would have straightened the horizon/pathway a few degrees so it doesnt appear to be tilting to the left. Crop a bit of the bottom off the shot too. Not too sure about the sharpness either.
image seems tilted to the left. Seems to be an act of carelessness rather than artistic intent. the people are nice, but the trees make the compostion seem too centered. the sky is boring. the sidewalk in the forground could have been cropped out for more impact with the reflection having more space.
