Hi guys,
Are you ok?
This is my lastest study. I try made a realistic packshot.
Comments?
Looks good so far! I think the plastic/glass looks just a little too thick. Keep it up!
It’s looking better!
some things:
label is rather plain
background is usually (sometimes) whiter (doesn’t have to be)
reflections on the bottom of the bottle from the backdrop seem a little odd.
orange material seem really thick (if this is supposed to be orange juice)
the second one is much better 
i like your design
