I think this fits the challenge - I don't think I have seen a picture of a jump rope on here - but I feel the photo is lacking something more of interest. But I do really like the DOF - I am a fan of shallow DOF.
I like this, simple and uncluttered. I think I'd have like to have seen a little more of the rope in focus and do like the oof handles. Nice colours! and I'm sure it has been mentioned but surely its a Skipping rope? (singular). Good luck!
It's not exactly a new subject , but it's rare here, for sure. I wish the handles were more in focus... more DOF would help this really pop from the wonderful black background instead of receding into it, I think. (not voting)
