Monday Marker Minute for Oct 25

Take a quick minute and see how I colored the stamped squirrel from the #CTMH Slimline Celebration Thoughtful Critters stamp set. On the first one I colored it "flat" using only the Brown-Grey marker (and the Earth Brown for the acorn) and on the second squirrel I colored it in with Victorian Blue and Brown-Grey and added in some elements to create more dimension. Which do you prefer - and how should I use this on a card?
