Poundcake - Big + Process (Patreon)

The process is quite simple here:

1 - lines/defined sketch.

2 - Base colors.

3 - Apply shadow with multiply layer.

4 - Add highlights with screen layer

5 - Add some corrections at important parts like the face (and color the tail =P)

6 - Merged and make the corrections with the brush to give a more finished feeling.
