My Art Workflow/Process for Beyond 8100 comic

I create initial page w pencil, pen, markers, charcoal sticks. Usually w rough layout, but a lot of times (ok, most) in final design phase, I resize/move around panels on computer. Highlight colors with pastel sticks, smudging out with newspaper (works better than paper towel!), and fingers. The colors are just for base, because I do my light highlight color phase in Photopea and GIMP. Then scan, take my individual panels into Photopea/GIMP and past into new layer to make layout fit my page and also resize based on banner I'm using. I do a lot of layer work, for tone, glows, adjust brightness/contrast, clean up my sloppy marker work, add text, banner, etc. Been using Photoshop for most of my 25-year graphics career, but now that I'm retired, I didn't wanna pay the subscription (and fuck Adobe!!) so now use Photopea and GIMP. Photopea mostly since it's most like Photoshop, but I'm learning GIMP. System is Linux Mint, Cinnamon 6.4.8.
