The Call Santa vendor struggled with meeting the brief for the character designs, which were a critical part of the success of the experience. Below shows my feedback and iteration process with them.

IV Studio Char Design v1 (not approved - passed feedback requesting to age down and round out shapes, going for Pixar style rather than Cartoon Network)

IV Studio Char Design v2 (not approved - needed stronger silhouettes and friendlier eyes)

I provided rough character sketches below based on principles I had learned at Pixar (ex. strong silhouettes/shapes, body proportions, etc.).

IV Studio Char Design v3 and v4

IV Studio Char Design v5 - approved

Success! (painting from voicemail message)
