I am following some tutorial in The Graphics Fairy website, which are quite simple and good. They are designed for Photoshop Elements, but I use Photoshop CC 2018 and they are easily adaptable. For me, Photoshop is easier to use than Elements anyway, and I find it to be more complex but, at the same time, simpler to handle once you are used to it. This tutorial was mostly for colouring an old postcard and also for creating different layers by altering blending and transparency. I have used most elements provided but added some of mine and also came up with my own version of Marie Antoinette's portrait.
