Just snapped this pic on the way out the door. I'm not really seeing what you mean about Boba Fett. He's shorter as he should be and the scale is right on IMO.
Thanks for the pic, that really helps! I think it's just the way my figures are posed. IMO, Boba is way bulkier than Maul, but I can see now how Han and Boba are pretty much the same height.
