Very intense-looking stars!
Great work, these stars look strange and alien, as if they belong in very distant solar systems.
I especially like blue #3, red #1, red #3, and green #1, #2, and #3. The blazing solar flares look really powerful. I don't think I'd want to get close to any of these stars though, I'd be scared of getting instantly fried.
Blue #1 and blue #2 look too "blobby" in my opinion.
