I really like the piano melody and the harmony and texture movements!
I think the mix could get some cleaning done, although that might be what gave it that pyshcadelic vibe, so maybe don't? :D
The only thing I felt a bit short was the take on the theme, it was good don't take me wrong, but I felt it need a bit more overwhemingness, in other terms, I felt aI was near a river, not a great water fall
Continue the great work, take care :3
