Just beautiful! I like the design of this and the colours and... there really isn't anything I don't like except the title as this doesn't match my personal stereotype of a supernova. I like "Galaxy Star", though. Not sure why since it doesn't match my stereotype of that either.
This is a very beautiful picture and it will make a great desktop. I enjoy looking at other artist pictures they post on Caedes to see others point of view and ideas. Great Job!
