This is a great idea, the colours are wonderful and the background disappears beautifully. I think the crop is just a little close, a bit more outer black field would be better, and also the focus seems soft.
This photo does not appeal to me. Firstly, I am not a fan of this sort of set piece. The photo is noisey for no apparent reason. The colors appear over saturated. Focus is too soft. And the subject and composition don't rescue it for me.
Don't dismay. I have submitted photos like this in previous challenges. Live and learn.
Lines, yes, but "leading"? Not really. The lines ARE the subject, as it were, and they don't actually "take" us anywhere. The lighting seems rather pedestrian, also, and the pure black BG is adding nothing of interest for me.
