THIS IS CONSTRUCTIVE CRITISISM, I AM NOT TRYING TO HATE ON YOUR PIECE!!!
Hello! Love the idea of your piece, but I think that it is a little too smudgy. Also, Somewhere in the piece I can see some colouring errors, it would be good if you just zoomed into the picture and looked for them. (I do that mistake a lot too!) MY favourite part of the picture has to be the tree. It is nicely shaded, and just pleasant to look at. The water flows in a weird way, I would suggest looking at some references. With a little practice, you will become an amazing artist, keep up the good work! :)
Also, please excuse my grammar, I am not from an English speaking country.
