I guess you are getting good in this style. If you are planning to make another don't make the orbs monotone and make the background pop the focal instead of using black put more sparklies, or low opacity shapes or unsaturated things. Just make sure the bg doesn't bring away attention.
Oh and when you work with fractals on lighten or linear dodge, make sure to check for those unwanted bits floating around the edge. Try turning off and on the layer to see where they are.
