Very evocative, I like it.

I know this picture is old, but felt it's worth asking. "I noticed the shade of green in your pic. This is usually rare to see irl, so was wondering if you put green in intentionally, or was it an accident?" If an accident, one thing I'd like to suggest, is to invert the direction of colors.
Instead of going yellow, to green, to cyan, to blue....
Go Yellow, to orange, to red, to magenta, to violet, then finishing up on blue.
It helps get rid of the green layer that isn't usually there.
