First, I started with the pale moon colored grey and outlined him. Wanted to be sure I wasn't going to give it too harsh a line by starting too dark. Made that mistake a few too many times in my own marker drawings. Then, I gradually went in darker and darker until I hit the black in spots to emphasize this leaping bunny wabbit.

Next, I thought the mooon needed to glow.  You know, that ring you see around the moon sometimes?  It can be reddish or white or any number of other colors, but you often see it around a full moon like this one.  So, I grabbed the lightest peachy pink I had because I wasn't sure what the color would do on the purple background.  Boy was I shocked how much both that peachy pink (pale european skin color) showed up.  Then, I tried that almost white, can't-even-see-it-on-white-paper-sometimes grey. Yowza, that was a glow of a different color. But I liked it.  Then, I wanted to include some of the purple blue tones in the glow and grabbed the blue.  Just a hint, just a line or two.  No more or it would have overpowered the moon and no longer looked like a glow. Then, ya gotta start figuring out how to fix it or make it into something else cause it wouldn't be a glow any longer.  I really like how it looks. Really glows, you know?
