How about a little more inspiration.  This elf is new to the store and has the cutest little grin.  I had fun coloring up this one…ok, I have fun with them all…who am I kidding.  If you look closely you can see I followed  the sketch challenge from the MIC fan FB page.  Notice how the light source is coming from the right?  Do you want to know how I choose my light source?  A nice rule of thumb is to have the light source coming from the direction the character is looking.  This would put the “sun” in this elf’s face.  It draws attention to the “main” focus.  If the elf was looking to the left then that would be my light source…and of course if the character is looking straight at you the light source would be in front.  I hope that helps.  Now go color something!
