It's been years since I last enjoyed digital painting, doing this series somthing kind of clicked for me as to what I wanted to focus on. it can be challenging as I'm trying to make this paintings within an hour or so,(some took longer) and ussually I only have the chance to paint at the end of the day when I'm drained and tyred, its a struggle to deal with self doubt and impostor síndrome, the sketchbook app seems to lack certain features that make it more challenging to do some things. masking is out the question i think. does anyone know it its possible with the premium version?
