As requested a look at my workflow for this project, the client needed very high resolution images for a congregation Powerpoint presentation
I used pure Sketchup Output at High Resolution 4048x3072 with shadows on and without lines, and a second output at the same resolution in Black and White with the Permanent Marker Heavy style no shadows. I used a Photoshop plugin called Alien Skin Snap Art 3 to apply a Pencil Sketch filter to the first color output. I then composed the 2 images together in Photoshop using multipy to overlay the B&W lines. The final result has a loose sketchy look that explains the project without committing to fine details.
This is what a section of one of the final images looks like at full resolution.
