well, i didnt see this as a very creative piece, seeming as you just made a frog open a box and that was it. the wink was also too cliche'd

i think you can also work on your puppet movement to make it look more natural. It looked the like frog didnt know what to do with his/her arms

Great job - plus your frog sculpt looks really nice.

Very cool. The frog is IN the box. Very nice touch
