Tools trackers is a series of short, supernatural fiction, stories written by author Kenzan Akita. Available on Kindle. The covers are designed and drawn in pencil then inked over and gray tones added in Adobe Photoshop. The color cover was also done in Photoshop. There are a total of 9 covers, with three of my favorites shown above. Usually before choosing a design, the author was given three options in sketch form to select from.
