Thats awesome for only 2 years of playing the piano! I cant make something like that and ive been around pianos for 10 years! Bravo! The only suggestions I have are to start small and childlike and develop it from there, rather than starting big and staying that way. Its about water pouring, so why the heavy chords? Personally, I would try to incorporate a tremolo in the high notes, to show the sprinkling of rain, and maybe descending, sweeping arpeggios to show how the spider gets washed away! and because the spider has to climb the spout again, following getting flushed, bring in a small, tender, progressive - shy, but determined version of the melody.
but then again, like i said, I couldnt do anything you just did, so maybe dont listen to me! Bravo!!!
