Heiratic versus dynamic here. Both are drawn in ballpoint pen and colored in with marker. The first is more original, drawing from a number of references and modifying them all to some degree. I just added some razzle dazzle to the second one. Looks like Deedlit's sis or something. Pen forces you to cover your mistakes and make as few as possible to begin with. It took several years to prefer pen to pencil, but I do now. I need to go figure out why.
