Don't know who the author is, but I feel the HDR has been overdone on what is probably an amazing shot. The sky is just too muddy, IMO

I agree. The HDR on this one I knew would be hit or miss and myself even though it needed more blacks and the sky was blah. Fell in love with the coaster going by but the sky was too much. Thank you for making up my mind for me. I have changed the pic. What do you think now?

oh and I got away from the HDR on this one. It wasn't working right.

Glad you did... I am a fan of HDR but you got a higher vote without it here.

Definitely much better
