Tried the Windows version of Autodesk Sketchbook this time, with an actual drawing tablet. It had its ups and downs -- the sketching part went great, but the inking tool seemed jittery and inaccurate, which I suspect might be some kind of configuration or driver issue. It also failed miserably to export a version with layers that I could import into Clip Studio -- it was missing layers when I imported for some reason. I finally got it into Clip Studio, one layer at a time, to do some simple fills.

So, all in all, I think Sketchbook has some potential, but I see no reason to use it over Clip Studio, which has more features. I'll probably keep using it on my phone, though.

Anyway, have a quick drawing for Mermay!
