yeah Mothra is big in the film, but that size comparison looks like a little more fluff was pumped in for the figure. I guess it wouldn't be a bad thing persay for a little bit bigger size.
Though on the wings, they should have made the wings differently so you could flap them down. I know the wing separation bit may be nice, but it wasn't something characterized as a normal look outside of Aqua Mothra. They should have made the wings more mobile in angling down like in the movie...
