Looks like your patience and 'offerings' paid off. Good capture with a nice clear/clean background. Of course if the chipmunk were a fraction sharper, make this even better, but you know that, plus obviously not an easy thing to do. Looking at all the Chipmunk Story shots, looks like there might be a couple of good sets of triptychs/whateverptychs there.
Look at that little, greedy fatso! I love the perspective of him on the deck -- I like to stage alot of shots on a deck rail as well (good lighting and a natural look).
My Chippers ran off with a hot dog bun at my 4th of July BBQ.
Keep taking those critter shots -- you just can't pose people like that!
