An important part of creating illustrations of imaginary things is making sure you know what the heck is going on. There is a race of genetically engineered aliens that run around in the world of Mad Piracy and part of keeping some continuity is establishing basic information about these characters.
A "Turn-around" is a drawing of the same creature or character from the front, side, and rear. It is really important for understanding a character three-dimensionally. These character sheets are commonly used for video games, comic books, and animation.
Now you can look at a turn-around character sheet I did for the Europan aliens. Please enjoy!
