Do my eMax crowns need to be reshaped, redone or left alone?

I just got four front emax crowns done and I am concerned they look "off". They are different than my temporaries because I wanted a less square look. I tried them on in the dentist's office before they were cemented and even had my husband come in and give a thumbs up. I'm not sure if it is the size, length, shape, bite - or could it be that it's so different than my original smile I just need to get used to them? Any advice would be appreciated. Thank you.
