As a Lead 3D Artist at Jam City (previously TinyCo), the first project I worked on was the Marvel Avengers Academy mobile phone video game. It was a super fun project working with great artists such as David Nakayama. The characters are flat lighting based with a connected diffuse texture, environments are the same with sometimes an added baked lighting texture. All textures are hand painted in Photoshop.
