With a roundish face sometimes shortish hair makes it look rounder.

If it's a new salon maybe tread carefully this time then when you know they can do a good cut get it changed. Nothing worse than a hairdresser who will not listen and does what she wants, not what you want.
It can also be thinned out. I get mine razor cut as it suits my hair type and it sits alot better than a scissors cut.

Don't worry about the rural lot, they will notice and maybe not comment to you but I have heard my brother come home and mention that 'the girl in the bank had her hair done and it looked nice'
