I am in the midst of classwork with Heather Michelle, aka, Heather The Painter ~ this woman knows her stuff and presents it in an easy to understand way through PDFs and videos. She will walk you through each and every step of her process and she will supply you with excellent images to work with. While portrait work has always seemed far too difficult for me to even think about, I am learning a great deal.
There is a lot of room for improvement in this work that I am sharing, but I am enjoying the process.
The original image is from Ralph Melvin and was supplied as an example to work with in this wonderful class.
