I love so many things about this piece! The colors are beautiful and your style is something that I would be happy to create half as well.
I see what you're saying about the two focal points fighting. One thing I noticed is that the color split feels like it's right down the center (bright on the right, dark on the left). If you move the color split closer to a third, or maybe blend it a little more, it might ease the "two-sides" thing that's happening.
I also wonder if moving the dragonfly down into the center of the light (or moving the light up) might help add focus to him. Right now it kind of looks like his feet are the focus and that you want the viewer to see those instead of his torso/head/wings.
Just some thoughts. I am so excited to see the final product of this! Really beautiful job.
