This is a sketch idea of a concept I came up with in thinking about what elements mean to me.

The visible light spectrum is 7 colours, like a scale, I started with red (fire) and went around clockwise. funny coinky.dink green exists between yellow (air) and blue (water).

since this challenge is closing before I can get the real work done, a couple things might not be apparent.
Orange is air and fire, and to me that meant orange sandy desert.
Indigo is where earth and water meet and is missing the underwater mountain ranges blending into a coral reef.
One thing is definitely missing from the original concept, I wanted the infinity symbol broken into 4 puzzle pieces that each hand would hold, implying only thru unity can infinity be attained, reiterating the cyclic nature as well. But in smudging in the infinity symbol, it took the shape of an owl, so I pushed that in a little bit, as that works well if not better.

The astrological symbols apropos to each element were also imagined much cooler looking.
It's really hard for me to do godrays with paint shop pro, and the whole thing was supposed to be superimposed over a nightsky starscape...
