Here she is, the penguin that graces my icons, watermarks and signature - Niska the punk/rockhopper. (With some altered design and high stylisation.)
She came out more goth than I wanted, but I still love her. The camera couldn't catch the fluro purple, either *grumble*.
15cm tall at the tip of the crest.
