Looks very artistic to my eyes Nirlep. Going B&W made it more artistic in my view. I am tempted to say black at the bottom seem to overpower a bit, but cropping it will hurt the composition.
Having tried various random experiements with different kind of camera motion I had (rather still have) difficulty in accepting that as a right approach to create unique perspectives. Most often than not we end up tagging a meaning to the final output which was not pre-conceived. But in this case your experiements are not random - it is driven by relative movements of subjects far and near while you are in motion. Looks like you have found an interesting possibility. I am not confident of pulling this off however
Thanks for sharing.
