|Hi. Welcome from the Critique Club. First let me say that I gave this a 6 during voting and that was well above the average I gave out for this challenge (Extended Editing does that to me sometimes). That said, you have great detail in this image. Don't know if that says much about the equipment or the photographer handling the gear. At f6.3 I'm going to say it was the photographer doing an excellent job with DOF.
First impression when this image loads is the 'Bling' of the X, then it's a competition between the abstract quality and the background ferns. Regarding the abstract feel of this, I like the perspective you selected, it's unique. The diagonal works well for adding some tension (non static) to the comp.
Now those ferns ... I can't tell if they're close in proximity or distant. Being that the shape hasn't been lost or smeared by bokeh effect I want to say they're relatively close. If not, I want to know how you did it. :-) Was it another image blended with the bike?
You placed darn near in the middle of the results with this. My guess is that while it's interesting, the abstract is a bit much for some. The one nit from me is the grime on the black (chain guard?). If that was clean it might have made a visual impact difference. The ferns are really cool looking, but maybe not the best match with the semi-dirty abstract. Sorry if I'm not expressing this opinion on point ... I guess what I'm trying to say is there are two great components here, but not sure that they were the best pairing.
I'd say keep at, etc... but you're a seasoned shooter so I'm fairly certain you'll keep tossing some high scorers out there!
Just one persons opinion. :-)
