i took a crack at editing this image, & as always, i'm sure the RAW file would produce better results. if you're interested in having me work on that after looking at this edit, you can email the RAW to me at firstname.lastname@example.org.
i like this image, but i don't/didn't find a lot of detail to pull out of it with the upper 2/3 of the image being primarily green, & the lower third being essentially grey/brownish. the waterfall is nice, but a good portion of it is blown out, as is also the case with the much smaller little areas of rushing water. compositionally it seems a little loose with a lot of dead/wasted space particularly on the left side of the image. not having been there personally, i can't suggest how you might be able to tighten up the composition, but if you have access to this area without a huge drive, then maybe you can look around & find a 'better' way to feature the waterfall in its environs. (i am assuming it is the waterfall that was your primary subject)
it appears to my eye that the dynamic range of this scene is just too high to shoot - i haven't tried to see if i could get any exif data on the file, but if i was to guess, i would say the shot was taken under a fairly bright overcast sky in some portion of the mid-day (anywhere from say late-AM to mid-late afternoon). if true, not the ideal times to take a shot like this . . . but i also understand you can't ALWAYS control when you're at a certain place. but when you can, this time of day is not typically condusive for shooting waterfalls.
anyway - enough of the critique. i am attaching a file of my edit. . . & like i said, if you want a better version, i'd be willing to give it a shot on the RAW if you email it to me.
