Eekay's grin.
If you read Thirteen Ribbons - and if you don't, quickly catch up before I post the next part! - you'll recognise the rather egotistical character of Eekay, a snow-leopardess who simply can't imagine not being the apple of everybody's eye. Now zie'll be showing up in my usericon, thanks to the awesome talents of Azrin Derat! If you'd like to see a larger view as part of the badge I'll be wearing at Further Confusion, take a look at the image on FurAffinity. Also, while you're there, commission her for some art! She's got reasonable rates and, as you can see, she knows how to get an expression dead-on. Check out that grin.
