You've thrown my favourite colours and element into one thing XD
Must be a very gentle trickle of water or a seriously deep pit, there's hardly any rebound :D Round shapes can be a bit of a pain to draw in perspective, I remember really struggling them in tech drawing. This one looks fine I think :)

Definitely struggled with spiral perspective for a while, but really worth it ^^
