good perspective shot - but the sharpening has left to many halos ..
next time try sharpening in the L channel of Lab color space
that doesn't leave the color change halos (as bad)
this image has potential. love the lines and angles. don't you just hate it, though, when the skies are interesting everywhere but where you want to shoot! i do like the detail work up underneath, and i really like how you brought those details out without it looking like an overdone shadow/highlight adjustment. good luck in the challenge!
Nice, but I can´t help but wonder if this wouldn´t have looked spectacular if it had a nice sunset or sunrise behind it. Good effort though, I like the composition.
