Also it didn't look right for the longest time when I had the underlit shading layer turned on --- turns out all I had to do was reduce the brightness of the base color layer and suddenly it looked brilliant. I have to remember the effectiveness of darkened colors/lighting more often in my work.
Wheee it was fun how I did it too --- I just did a shadow layer set above the color layer set to Multiply as usual, then I copied that shadow layer and inverted it, then set it to Screen. Then I erased the lit up parts that should be be shadowed instead of lit up. Bam, you get this effect!
Yup. But I never used it. Believe it or not, I'm still doing that Now Arriving remake (getting back around to it now,) but this drawing of Maia was scrapped. But I liked it as it was and decided to use it for something else.
