It seems to me that main subject matter is predominantly to the left hand side of frame, the shapes and different colours, so including the right of frame seems unnecessary and detracts from the cohesive synergy in the right of frame.
Were it taken vertically that would have solved the conundrum, but perhaps a square crop, removing the 50% right of frame?
The yoni is invoked here, the squiggly path, the green and brown, the delineation lines of white and the black eyeliner, a soft limited colour palette, it's lovely.
The “hue” which is 180 degrees away from orange / brown - is the primary colour “Blue”. A darker, greyer “sea blue” would be the natural opposite to brown. Your green and your blue are clearly tertiary colours and contiguous to either other on their wheel.
Is this okay, to reply with an example? If not, please excuse me.
