Experimenting with Texture Styles

I've been experimenting with different ways of showing a wood texture, using different combinations of assets

Illustrative borders in brown and black

Different styles of shading



Wood grain in different colors
 

Here's a few combinations on the model, Anyone have any thoughts?

Light Grain with Dark Outline

Harsh Shading, Dark Grain and Brown Outline 

Soft Shading, Light Outline
