Nice work, I like what you did with this, all though I do see what you were doing, I would've placed something in the center to get rid of the void but other than that, this is very good, also a little bit of an increase in contrast and saturation couldn't hurt. Nice job.
Nice flame and choice of gradient, and sorry to say, but yeah, that black hole seems rather large to me, I would prefer to see it slightly smaller. Good job, though, keep up the good work! =]
If the automobile had followed the same development as the computer, a Rolls-Royce would today cost $100, get a million miles per gallon, and explode once a year killing everyone inside.
