Very nice, you should do well with this shot. The only thing that keeps taking me away from the center is that darn crane on top of the buildings on the right. I might have cropped this to remove the taller building on the right, I think people would still get the centered theme even if this was tall and narrow.
Looks like a post card almost. I like the colors, the reflection adds the perfect touch. Even the crane adds to the entire effect. Did you get any shots from 5-10 minutes earlier? A little more red in the sunset would add lots of drama.
I suspect this should do quite well. very sharp for a sunset picture. not too many blown out highlights, which is rare for what I'd guess is a pretty long exposure. Great work.
You picked the perfect time of day for this shot. Colors are magical. I like the fact there was enough breeze to give a hint of rippling on the water surface. Normally, I'd say to crop out some sky - as it's not needed..... but then it wouldn't be centered (slap my typing hands!). Overall an excellent image with high finish potential.
