Sounds good to me ! Sure it's OK. She should like that as it's a nice thing to say!
I just told my girlfriend " you have the looks of a model, and the spirit of a angel". Is that okay to say?
As long as you are sincere about it, it was a very nice thing to say.
What would it matter what anyone else thinks about it .. What matters is what SHE thinks about it.
That's a very nice compliment.
Thank you she liked it
