Another page of digital sketches created in Photoshop.  Further exploration of folding stool ideas. 

Trying out my new Surface Pro 2 tablet for drawing.  I did this ideation page for a folding stool I am developing in Photoshop using the Wacom stylus that came with the Surface. 

Continued work on lighter sketches.  I also added greater contrast to previous sketches I had drawn and am therefore re-posting them. 

These drawings show a progression from orthographic sketching to perspective sketching.

The first perspective rendering of the screwdriver I wasn't confident enough in my line work and many flaws could be detected when observed closely.  I attempted to solve that problem in the final rendering.    

geometric shape marker exploration

continued exploration of elongated lighters using tracing paper and one value of marker from both sides of the paper

rapid visualization of lighter concepts

this piece was done using one value of marker and a pencil on tracing paper

gradient in the marker was accomplished by flipping the paper over and drawing on the back

final rendering of ideas explored in previous sketch pages

continued exploration of shoes
i was particularly interested in the idea of making a shoe that was comprised of just two or three basic organic shapes
