Here are two blends using just good old Suzanne. The experiments focus largely on distortion and painterly feel using the node editor, and colors manipulation using the Diffuse section of the Materials settings. Key aspects:
- The RenderLayers output are the monkey heads on a transparent background
- A noise texture is used to with a Displace node on the monkey heads to create a rough-edges paint feel
- A wood band texture is used with a Displace node to distort the monkey heads shapes in a psychedelic way
- The monkey heads are mixed with the paper texture via a Soft Light node and overlayed onto the paper with an Alpha Over node
The paper texture is from cgtextures.com.
