Nah, no need, only to demonstrate something
IMO, this makes it stronger
Removing the shadow area at the top helps unclutter the image, also I don't think the bike is the subject of the image... So I think it works better cropped half out. The way it is now it just acts to point the eye to the real subject, the people!
Also, cropping out much of the road means that line on the road under the bike has the same effect...
What do you think?
I know I have cropped a bit, I not saying this to take any credit ...
In that format, it's a really superb photo! The timing of the shot is spot on, both in terms of the light and the shadows, and in terms of the relationship between the people you have captured!
The shadow of the bollards helps frame them, and the shadow of the chap on the wall sits perfectly ... Any other time of day, it would be a good photo, in this light, it's spot on!
