Aqua green/blue is my favorite color too! =D It was fun making her. For the design: The star marking over her eye is only on one side. The star markings on her flank are on both sides. I decided to do a fish/dolphin/shark dog because you seem to like them. ^.^ Oh, and those are mini stars in her hair.
Credit to @hibiscusthedog for the contest and a few ideas for the design. I'm leaving the name up to you.
