I think the prominent chin suits her! She is a milk maid type, Working woman. Owning upon well making a living the hard way!
Like the good old days, She also has a very Western classic appearance... Back in the western times, A lot of the women did have chins stout like that. A well husky worked out woman would show such a fine chin, Due to her efforts of over working and as one would say "A stiff upper lip!" ^^
