Owen! Good to see you back, mister! Maybe we'll see you in chat?
I agree with Steve about the flat colors. You don't say what speed film you used, but perhaps Velvia100 would have made the greens pop a bit more? I don't much mind the subject right in the middle, myself, mainly because you've captured a gorgeous waterfall here, but perhaps a little more off-center would have worked for something this long and dividing. Still, it's a gorgeous subject. Nice.
I think you've got a really nice subject here, but the photo seems so washed out. Can't tell if it's just overexposed or some PS adjustment needs to be done. Also, maybe the falls is a little too much dead center. Either way, the exposure on the water seems OK as it looks nice and silky. Thanks for sharing.
