It's hard to get a good shot of Stinky Lessa Sweetness because she always looks grumpy, even when she's not. That, and her face is dark and hard to expose properly. She's also scared of everything, so it was hard to convince her that she wanted to sit in the light when it was just perfect.
Therefore, she's annoyed. Or maybe not. Who can tell with a cat? She always looks that way.
