Illustration made for the Monthly Character Design challenge. The theme of the month was “Living Buildings”. 
My first idea was to create something similar to those old houses found in the UK or Pyrenees where a big surface of grass covers the top of it. Then, I decided a cat sleeping would fit the idea, since their body shape when they are laying down has a soft triangular shape, perfect for it to look like a house roof.
Just for the sake of silhouette clarity, I decided for the cat to be yawning.
On the colors, I decided to frame using similar values but different Chroma, hence the use of reds and blues.
