Straight up, eye candy

Very nice piece I love how the colors pop off the page. You also have a good technique in your stroking, the overlapping white/blue lines circulating around the base and outer rims of other colors of the supernova give off the feel of movement.

The only thing that annoys me is that you snapshot it rather than scanned it. I hope this is the full project I'm looking at cause it's pretty cool. If so then I think you should've centered your work in the middle of the paper, it would make your composition(placement of your art) look better and give a stronger feel of depth but the perspective feel works.

Also you should work more on overlapping colors as I feel the yellow steak should be overlapping the source of the supernova would look better rather than being outside of it.

Overall:
Well done, your colors and painting style definitely represents the basic Idea of an occurring supernova.

Also abstract means your art is visually independent from the creations of the world. In even simpler terms your art is not based on objects of our world.
