Hi Rachel,
Of course your photography is getting better but I can say this only compared to your initial work. I haven't got anything to compare this particular picture with to say if it is better or not.
I took the liberty of playing with the white balance, tonalities and sharpening a bit. I also cropped out a small portion bottom right.
What is left is a nice snapshot but your subject does not jump out of it as it should. Framing using branches is a good idea, but this main branch in the front is obstructing the waterfall.
You should have tried another angle to get a better shot with less obstruction. Preferably, one showing the top of the waterfall.
HTH,
