It’s beautiful

Wonderful work on the colors, It seems a bit empty in some places though.

You have an interesting concept here, but there are a few things that can be done to strengthen your composition and give the piece a stronger overall tone and mood. Right now the objects in the composition are competing for attention in an unflattering way, the colors of the background are very vibrant and have a generally nice look in the coloring, especially against the black of the stars but their positioning in relation to each other is making it so none of them are working in harmony. The shapes the trails take should be reworked so that they guide the eye to a focal point and the colors should work together to push the eye along that one "trail;" right now from the bottom to the top you have blue to orange/red/yellow branching to green and almost leading to magenta; those colors have no logical flow with the possible exception of red to magenta, but its more on the orange side so this leads to a color imbalance of sorts. The way the green branches off of the red and leads to nothing really throws off the flow and because its a lot like the red one in terms of shape you have this effect that makes the center feel much busier while making the top left feel more empty and throwing off the balance of the background.
The issue is exacerbated by the actual intended focal point of the woman sitting cross legged in the rectangle. Straight up ditch the rectangle and make the girl blend in more to the space, right now the way the rectangle is colored breaks up the composition more and further scrambles the focal point. Use those colors to your advantage, right now you've got a mostly cool palette going on back there with the blue green and magenta so in I'd say play that aspect up some more; get rid of the red one and make the figure of the woman red/yellow/orange with white highlights, then have the colors arranged in a way that leads to it in order from least intense to most intense color. With the woman being more connected to the background than she currently is you'll have a much more unified drawing as well as add greater to an idea of unity or connection with the universe than what the rectangle is providing.
You'll definitely want to study up on some composition rules and guidelines, like the golden spiral/section/ratio and balance for further information on how to better compose the image you can check out the composition tutorials on the art101 page here at Newgrounds.
Good work, hope this helps in some capacity!

Like the colors.
