I think that picture is gorgeous. Both Chucks are 2.8" around. The Little one is 3" tall and the big one is 4.5" tall.
If you crop that enough for a Little Chuck, you are either going to lose the lightning or Nessie is going to be all the way on the side (and she'll be by the seam when it's done.) You might want to ask Jeff if he can move her a little to the right. Then he could mostly crop mountains on the left and you'd still have the moon, the storm and Nessie.
