Oh, that poor girl! If it's any consolation, I don't think bikes would be very useful under the sea anyway! And this proves that mermaids don't need motorcycles to be cool man.
High praise is deserved enough for rolling with my ridiculousness, and for doing a fantastic job drawing a motorcycle. However, what really shines here is the really subtle reflections of her bike (especially the color of her fins!), and I really like the subtle bend in her...I want to say knees, but I don't think that's what they are.
