After completing the first draft of coloring in the SKT, my technique improved to such a point where the First Septenary, i.e., the very first cards I started the coloring on, paled in comparison.
Literally. As in, like, I didn’t have enough color. I wasn’t going to redo all of the Majors. But the First Septenary (Keys 1 through 7), definitely.
Above, the top row shows the Magician, Priestess, Empress, and Emperor cards I first colored in at the onset of this third edition undertaking. This was around spring of 2020.
The bottom row shows the same four cards as I’ve re-done them just now, about half a year later, after completing the first draft of coloring for all 78 cards (well, 80 in my deck).
