From line to gray tone to color

This is one of the earliest designs I ever worked on that was intended to be digitally modeled in a CG program. The original Crash Bandicoot game was the first. This was something I did the following year in 1996. It was a project that involved some sexy girls. I'm not sure if it was ever produced. The concept drawing below was initially created as a black line sketch on the left. Later on in class at my school I went over a copy of the sketch with gray markers to teach my students the importance of tone. Afterwards I scanned the gray marker rendition and used Photoshop to add color to the design by tinting the image. Turned out nice.
