Here is the concept art for the Samurai Pizza Cat, "Polly".
I drew the concept art on paper, using images of Polly found on Google for reference, but I have changed her suit somewhat.
I scanned the drawing in, and the colour was added using Photoshop.
Here is the model I have made in Maya (Personal Learning Edition).
Here is the wireframe.
And here is the texture map made in Photoshop.
I made the eyes and gems in the armour shiny by creating a specularity map.
