If it's a sex-reversing pentagram, then a cotton shirt would disappear because cotton is an appendage of the female cottonwood tree used to disperse seeds.
There are actually only 2 pages left. The extra 12 pages are bonus pages for patrons - just some behind the scenes sketches and thoughts, plus two alternate covers.
I scheduled this to be posted at 12:00 noon eastern time on this site and 12:01 eastern on patreon. I've moved recently so there may be some time zone shenanigans going on, but I've tested it on the this site and it seems to be working correctly.
The transformation changes body, hair, currently worn clothing, personal effects, and sex drive. She changes back when her lanyard is removed (most of the time?), that way he can investigate what various parts of his wardrobe turn into.
The comic has become more about the slow-build conversion than a fast break-in. Each encounter takes her another step along the path. She's not quite ready to fully live out her fantasies.
I had several sketches to that effect but as I wrote the full story, a more gradual psychological conversion emerged. At this point I don't think Alison would need any magical or physical convincing to end up on her knees.
>what's the light level on the bands indicate?
As established in the full Dark Altar comic https://satinminions.com/img/Dark-Altar-00.html the enchantment on the bands makes her submissive/lustful for her assigned demon partner. It may also have something to do with summoning him.
The first image was just a random sketch, but then I decided to make a little sequence out of it. I redrew the first image with her hair down later, it'll be posted next monday.
I definitely change to color of the scene intentionally to convey the mood, and I've tried to make different magical effects look different and stick out more than the mood lighting. The girl in Dark Altar is being directly influenced by magic, so her eyes glow. Mistress's eyes glow occasionally due to her innate magical nature.
I don't have an exact system worked out, I just try to make it look right.
I made this in my own animation program that I'm developing. It's very smooth because it's vector based with automatic interpolation. It's a bit tricky to animate lines that aren't visible in every frame with that system though, and I didn't really have the tools to fix things coded at the time, so I just sort of stopped.
I think a good way to do it might be to make everything see-through like you'll see in the next animation. I'll work on layering strategies once I get coloring added in.
