Another option would be to crop the left side of the photo away, leaving a portrait format image of your presumed main subject.
Please note that as an artistic image, I like it as it is. The geometry of all the legs is very interesting, and there is a lot of energy in the picture.
The main subject appears to be posing. Waiting half a second to release the shutter would have left a clear background on the left side, if that was the goal.
The main subject walked towards me on request. I did have another shot with the stroller lady gone, but the main subject's stride was awkward. I deleted it.
