Fantastic Voyage: Previs with Sound

As I work more on post production, I decided to multi-task and make the sound for my animation. There are bits I need to tidy up in terms of timing and volume, but I think it's getting there. I'm debating about taking out the growls from the three little bacteria (1:59-2:08) because I'm unsure that they match the animation and I think they might overpower the narration a little bit but I'm not sure yet. It might be my imagination since I've been listening to this all day and it's the last thing I put in. Any opinions or thoughts are appreciated.
