Hi James,
Where is this? Shooting falls is a fascination for photographers and there are, like romanitc sunsets lots of great examples. So it's tough to enter this area of photography.
These pictures are rather small. I suggest that perhaps that one of these might be worked at in B&W to carefully construct a composition that's attractive and has some authority over us. These pictures are all nice and enjoyable in themselves. However, what is your goal? Is it just a reminder you were there or something else about the place you want to get into a picture. Think about this and also look up waterfall pictures on the web and see what has been done n B&W and in color.
Each place has it's own character and when you can connect with that, there's more chance of getting a picture that will project itself beyond that moment when you thought it would be a nice shot. It's tough fro all of us, however, this is what we do here, we try to improve our own work and also encourage others on their own path.
So look though you images and see if you might work on one and make it a good 800 pixels wide so we can get pulled into it.
These fascinating falls are a nice down payment of this project. I do hope you have them in RAw and might consider trying this. What do you think?
