This is a reasonable Summery
shot with decent colours but for me it is missing that extra something which would make it really stand out.
I can see why you wanted to include the cloud but I actually think it is stronger with just a small amount of sky. That would put the little cascade up above the centre, where it would have more impact.
The cascade itself doesn't have a lot going on and is getting a little lost in the distance. I would be tempted to ignore those particular foreground rocks and move onto the next two, bringing the cascade closer. If you couldn't get that close you could try zooming in on it in landscape mode, then cropping into square format.
Another thing to try is a much longer exposure (if you have ND and/or polarising filters, which would make the water show up more.
Finally, with regard to presentation. I find landscapes tend to work better against black (or sometimes white) backgrounds rather than the mid tones.
