This is a good start - maybe you need to consider a horizon line and taper the stream away from you so that it fades away.
Another thing is that you have the river over the front of the tree.
You should maybe consider drawing and painting the sky line and horizon and then the river coming forward.
Remember you need not show all the river - let the viewing person decide that - it adds excitement.
I love the fantasy element in your painting with the large mushrooms.
(I hope they are mushrooms - apologies if they are trees
)
Fade the river after the bridge and look from a lower level of perspective rather than a birds eye view...
