CK I beg to differ. During the course of my life I've been called names like 'horse' and 'chin'. My face was terribly long.
by length are you referring overall length? yes, the underbite exaggerates your features and makes everything appear out of proportion. the reality though, is your features are well above average. the distance between your lips/eyes/nose (midface) is ideal...not remotely long...not at all....when compared to the majority of jaw surgery candidates.
your only issue was the jaw.
