Seems I’m alone in this, but thought I’d try a little experiment. I drew the sphere in pencil, but also wanted to have a go with my new XP-Pen tablet. Couldn’t decide which app to use, so tried the three I have installed.
So the 4 versions of the sphere are:
Pencil, Krita, Affinity Photo and Bleank Black Ink
The pencil version was by far the easiest to do and had the best result. I think Affinity Photo was the easiest to use, then Krita with Black Ink being a little more unpredictable and fiddly. Overall though, I was pretty pleased.
