I have downloaded Krita 4.1.7 and when trying to use the brush presets they weren’t looking like they were supposed to, when I tried using different ones I noticed they all look pretty much the same and have the same problem. Pencil looks just like pen, pen looks just like paint brush, really frustrating because it looks like it would be a really good programme for a hobbiest like myself looking to get into digital illustration.
If you want to have dynamic strokes, you need a graphics tablet and the drivers of that tablet installed. The budget wacom and huion tablets are not terribly expensive and recommended. Also don’t forget to install the drivers.
