Looks ok to me. I have some barteri ina low light, non co2 setup and the leaves look just like that. Old and new both hade some "ruffling" I think it looks nice.
What are the conditions in your tank. That leaf looks a littel yellow to me, like it was deficient in soemthing. HOWEVER, it will take a week or 3 to adapt to your tank conditions and whatever it was missing should be replaced in your tank. I would not worry about it
