at first I liked the subtlety of the first one, but looking at the details of the center, I realized that the 2nd one gives you the opportunity to put in a couple of spikes of the the the very soft fairy fabric.
I agree with the coloring. Make several copies of your drawings and color them. If you have several shades of purple pencil, great, if you dont, then use a 96 box of crayons.
what I'm thinking is the large foreground starburst needs to either be split up, or it will take over, and you dont want it to do that, center needs to be the focus. If it is sunrise, or all purple, you won't see the center. What I think is make that your focus green, the brightest one (the "square" in the center). Then the spikes behind in your various purples.
Might need another purple divider like the one between the center & the first set of corners.
...maybe more ideas than you wanted. I know it will be lovely whatever you choose to do. :)
