Time of day, try shooting it in early morning or late evening instead.

Dont think anything can be done for the "wow" factor.The image is very busy with no clear subject. The waterfall is partially covered by a branch.I would reshoot, isolate one subject, shoot at a different time where the light isnt as flat

10 naked chicks jumping into the water? J/k. Sorry I'm a noob so I can't say much but I actually really like the photo. I think it defines the height of the waterfall well.

You could make it somewhat better with a bit of editing, but as mentioned carefully choosing the time of day and using a Circular Polarizing filter helps too.

Here is one approach. I warmed it up some to counter the blue cast in yours:

It looks over-exposed. It needs to be "printed down", as we used to say; the water looks too light; the foliage looks too light as well. A really skilled Photoshop jockey could breathe more life into this shot, but it would require some skills.

^^ That, and use a polarizing filter. Search the term 'golden hour'.

I think you might have already gone overboard with the sharpening at first, so I'd start with lowering that a bit. The reshoot is a great idea though, golden hour would be very nice.

Yep, I agree. My first reaction was that the greens didn't really pop in any way.
