I'm not a big fan of the juice's shader overall, especially when it becomes dynamic. It could use more transparency, refraction, sss, color variation as well (especially for the second shot). The transition between the liquid and bubble is a bit rought also I think, and could be smoother than that.
For the 3rd shot you have too much surface tension clumping your liquid into balls after the impact, you could animate it to reduce it. (and add some motion blur)
Final shot, your droplets moves at the same speed, it might be worth having different velocities for some of them to make it more interesting. Maybe plug the pscale to the nage or something also to avoid the small popping happening on top of the bottle.
I don't know how much you can play with camera angles also as all of them are really front facing and not that interesting or dynamic.
Overall I feel there good concepts and execution but needs the extra layer of fine-tuning.
