Great video . thank you for sharing . I'm a professional artist . I've had a XP-Pen Artist 12 Pro https://www.xp-pen.com/product/479.html Pen Display and I now only use my iPad Pro. It's more than paid itself off for me and I love that it's so compatible with my Mac.
As far as programs go, Adobe is adding more iPad compatibility soon and Procreate is incredibly powerful and accepts and exports PSD files. I do a lot of illustration work and using it to cut out people for my job.
I also love the red/pink glow of the city lights. Gives it an absolutely mesmerising look. Beautiful. Bravo.
