I like the shot. But at the same time, I wonder if the shot would be any good if it weren't for the unusual colors. But hey, a lot of shots don't have one good element going for them, let alone multiple ones. So, good stuff, bud.
And yeah, something is missing. I dunno, I guess it's like it's missing some kind of main emphasis? To me it almost looks like a background of a picture.
And, if I find the original, I'll post it.
I agree there is a lack of subject, but the lines of the trail make a decent substitute in my opinion. I'll admit without the colors I don't think it would be a good shot, but I think as it is, it's nice.
