My first Gumroad Tutorial video is now ready for purchase here https://gum.co/qDhkY The series has 6 hours worth of Video Content, and over 150 custom brushes included. Part one is a quick start to photoshop video series, part two is a demonstration, and part three covers design and practice related topics such as how to make a design document, research, how to thumbnail, various ways to study, portfolio and resume creation.
Edit: Changed the price, I thought it was showing in Dollars still, its £12 sterling now. Ive also uploaded my Introduction video as I believe it serves a good overview of what you are purchasing.
And here is a warm up sketch and timelapse.
