I quite like it, it seems sharp and contrasty (albeit maybe a bit underexposed, could be my screen though !).
The composition feels slightly off for me, with the sun being dead center. The lens flare bugs me, and i'm aware that in this case it was probably what you were going for, but the patches against the silhouette i find distracting.
Cool colours though, edited much ?
I think pretty much anything is sellable if you can find the right buyer ! I would like to point out i've never sold any photography though, but i'm sure others will have better advice.
