Some notes on the process.

I placed the scanned pencil art in Adobe Illustrator. I placed a vertical guideline in the middle and in a layer above I traced the left half of the carrier with the Pen tool. Once traced, I just duplicate and mirror horizontally the line artwork to create the full Ride Armor. Then I exported the results as a PSD file.

Vile was drawn and inked in a new sheet of paper. I scanned it and pasted it below the previous exported Ride Armor PSD file, to create this full line art.
