The crop will get rid of a lot of junk and focus more on the subjects (not to mention simplifying it a bit, even though I mentioned it). No evident pixelation or softening at 4x5 300 dpi.

Terry the crop would be fine. Every time I looked at this photo it felt lopsided. Much better to focus on the subjects in this case.
