Ok in this section I photocopied my sketch and made a 2 inch x 3 inch copy of my sketch to pick a direction in which my light source will come from. I rendered it out some to get a feel for what I want my contrast to be. This mini sketch rendering will serve as my guide once I import my final sketch into the computer. I used a set of warm gray markers ranging 2-6 (20% – 60%). My layering consisted of using warm gray 4 the most and reapplying after each dry set. I used rubbing alcohol to juice up dry markers, a quick dip usually does the trick.
Built up from a number 2 warm gray marker. The main focus was to establish contrast and separate foreground and background planes.

2×3 inch scans of my larger sketch. Working this small helps me focus on figuring out the lighting and where shadows fall.


Light is lowing into the interior from the driver’s side window. I chose to keep the background fairly slight and saturated to keep the viewers focus on the front of the sketch.
