I had thought to just paint a dragon's eye, but decided to go with something a little more whimsical - and this is the result. Lots of experimentation with the coloring here, and lots of general silliness too. :)

I featured this art in my 3 Magical Animated Effects in Clip Studio Paint tutorial, where I added a fun sparkle animation. The tutorial is available on YouTube, or a text version on Clip Studio Tips.
