02. Scan in your sketch and open it in Photoshop. Adjust the levels a bit to brighten it up then choose Image > Adjustments > Hue/Saturation and click Colorize to change the pencil lines to a very light cyan. Print this image out at 100% on another piece of paper and pick up your pencil again.


03. Draw back onto the paper print, using it as a basis for drawing details and refining the structure. This technique is similar to the lightbox tracing methods used by most tattoo artists. Refer to photos of snakes to create interesting skin patterns. Scan it back in. Open in Photoshop, adjust the levels, change the colour mode to grayscale and save your file.


04. Open Illustrator and create a new file measuring 14-x-16 inches. File > Place your saved sketch onto the art board and scale it to 130% and click a light cyan in the Swatches window to lighten up the image for tracing. Lock the layer, create a new layer and outline the sketch with the Pen tool using a 0.25-point stroke.
