The one with the ice cream is SO cute! *squees!* The coloring is great, and the expressions are priceless. Although... (hates to point it out)... Light's right leg is off. Unless he's part Gumby (which I suppose he could be--this IS manga, after all), it realy couldn't bend like that. Maybe he just needs a bit more knee and thigh?

The shinigami one is amazing though. Such jagged angles and general creepiness... your ability to draw monsters never fails to arouse my undying envy.
