I don't think this epilogue is terrible but there are several moments that don't make sense based on previous choices and actions.
Those inconsistencies with previous choices and moments in the story are where the epilogue drops the ball. These are also the reasons why I don't think it is particularly good despite not being terrible either.
One other thing I realized though was how short Lena's part in chapter 11 was. According to Eva, this epilogue was of the same length or at least close to it yet it still seemed relatively short (as should be expected by an epilogue not however by the main chapter).
