Modified Textures:

I modified these textures in order to increase and intensify their desired effect. I took a different approach with each one in order to experiment with the lighting and shadows.

Eliminated hatching to intensify the pattern.

Here I used an ocean filter to haze the drawn lines, this increased the shadow effect of the texture.

By inverting the colours I made the light to dark effect become dark to light. I also used a shadow effect to make the pattern seem to glow. After modifying this texture I think this one best shows the experimentation of light and shadow.

I attempted to filter these textures with a brown haze and add a blurring effect.
