Cool. I like the colours too. One can't say a whole lot about composition, because the 'usual rules' don't really apply to this one, but I do think the different colour patches lead your eye around the photo, which is good... you didn't frame it so you only had one colour area.
Closeups of the reflection areas would be fun. If you have similar conditions & can go back, try zooming in on just a little area, & shooting at 1/250 or something like to freeze it sharply, & see what neat patterns you get.
And welcome to the forum
