I really like the fact that there is graffiti under the bridge. Its somehow slightly artistic, its not overdone and doesnt draw a lot of attention. Its always nice to see peaceful nature scenes but sometimes I dont mind seeing a combination of that along with something man made, in this case also shows the destructive side of mankind as well.
I think its the way he cropped it, did you try cropping it straight down from the top instead of the sides? Did it bring it too close to the beginning of the waterfall?
