I think this great just the way it is! You've got your colors in harmony and a nice airy feel there. It's a bit on the abstract side but that's what makes it great. Viewers can find many different things in there. You are coming along very quickly Robert. Keep up the good work!

Agreed. It's really cool. And you're moving fast as the water in this picture.
Reminds me of Chinese brush paintings of hills and mist in a way.
It doesn't need anything. And I especially like how you've divided your space. Good design.
But. . . when a question like this arises, my recommendation would be to save this one and to take advantage of digital and make versions to experiment with. It's always good to know what would happen if . . . (fill in the blanks) if you were to add an element or a stroke or two or a different color etc.
Were I to try something, I would perhaps use this as base and try adding a few things here and there. So perhaps something that was static and focused.
The contrast would more emphasize the opposite. So by introducing a slightly sharper defined branch with a couple leaves as an overlay, or to one side of the water (or vine or something you would expect/want to see), you would make the water go even faster, emphasizing a thematic element of elemental contrasts.
But again, your guess is as good as mine whether it's needed. Doing it is the only way of really knowing.
