add emotion to vocal tracks

[Jt06]

for this specific project, its only acoustic guitar and vocals. recorded seperatley, but the goal is to make it sound like a live, all-in-one, performance. with that being said, we are intentionally NOT piecing together parts.. we'll do different takes, but the song is being played, or sung, all the way through.. (with all due respect, please leave negative comments on that to yourselves. each project is different and there are reasons to every approach.) on the vocals, the singer gains emotion as the song goes on. from verse 2 and on the emotion in the vocals are perfect. the first verse and first chorus seem like their lacking some emtion a bit. but the key and whatnot are fine. Therefore, we don't want to redo the whole thing.. what kind of mixing/eq can i do to the beginning to add some emotion to the vocals while making it blend with the whole song??
