Balls of energy (Abstract Art)

This is also my first abstract art using only gradient tool, marquee tool, lasso tool, smudge tool, and layer effect. Through this activity I learned that you'll have to save a PSD file (for layer editing purposes) and also a JPEG file.
This art is about formation of energy, which reminds me of how black-holes are formed.

P.S. I didn't save my previous work as PSD files, and have to use them as background. :(
P.P.S. Layering is so much fun to play with!
