Flower for my Mistress

I drew this on Halloween, so I might redraw these characters in vastly different outfits. Either way, I am intensely proud of this picture even though I know I need to fix a few things. Need to darken the colored pencil shading, the feet ARE a little wonky, and the scanner cut of one of the knees. But I love how the one standing up came out.
Done in ink and colored pencils.
Advice?

Characters are 100% original and my own.
