Aah, Klaus, congratulations are in order! Your creative eye is certainly serving you well.
I also agree with Laurence. May I suggest you add an extra 3 or so starbursts on top of the one you have there? Blur the bottom one quite a lot and increase transparency on it so you can only just see it. Blur the next a little less and a little less transparency. Repeat with last bursts adding less blur and transparency each time.
Keep on experimenting, my friend, it makes a difference not only to your life, but mine as well!
Sincere regards, Jim Roelofs
