Is this good english or not ?

[mummyloveslucy]

Hi, I'm writing a poem for my sisters wedding.
Does this good english or not?

With the biggest smile you've seen.

I know it should be You've ever seen, but that makes it too long for the rhyme.

I don't want it to sound wrong, what do you think ?

Sounds fine to me

Oh good. I've read it to my Dad and he said that it should be You've ever seen.
What does he know.

well give us a line either side...

Does this good english????
I must be tired.

Would 'With the biggest smile ever seen' work?

Could do. Thanks
