First Impression: A fun well composed shot that meets the challenge well
Composition: The composition fills the frame well but maybe a little too tight? Personally I'd have liked to have seen the ends of the laces on the bottom boot and both the laces on the top boot falling onto the background rather than the other boot.
Subject: A novel idea and whilst (for me) they don't appear to be cooming down the stairs I like the way they interact with the steps.
Technical: The lighting is a little uneven on the boots with the top one being a different shade to the bottom, both are exposed well but differently (if you see what I mean?)
Final thoughts: Top 20 for your first submission is a great result so well done, I gave this a 6 during voting.
