First design involve the user to assemble the tattoo from various components in the assembly area, while the interface interactively preview it on the body using 3D modeling on the left hand side
Second design aims for efficiency. It takes away customizability, and place heavy emphasis on showing how different tattoo would look and age. It allows the client to pick tattoos, which are organized by the artist, and place it directly on the part of the body that they are interested in. Similarly, if the user has their own design, they can drag and drop virtually any image on it too.
The third design is for the mobile phone, where the used can directly take inspiration from the nature. They take a picture of the lion, and take a picture of a part of their body -OR- pic a location on the mannequin. The algorithm will automatically combine the two into one preview right on their phone.
