I saw your pictures. You have a gummy smile, lip incompetence with visible chin dimpling, bimax recession with a flattish chin and increased anterior facial height, so technically you do have the classic earmarks for LFS albeit your case is not severe. You don't have a long midface because your nose is the same length as your forehead which means they're balanced. If you want to fix it and make your face "normal", you need bimax with counterclockwise rotation. Not many surgeons can perform it well, though. Gunson is the best, so schedule a consultation with him if you're serious about fixing this and have the money and motivation.
