I've been a bit back and forth with this one.
Straight off the bat I had the idea and style already set out in my head. This was more practice for me to keep my design work tidy, avoiding stray vector points under masks - in fact hardly using masks at all and cutting out overlapping paths.
I stuck to a stock image bottle to produce a 3D preview. Mapping the label on the 3D bottle didn't seem to work with these complex images I created. I really didn't want to go back and change anything so I went with a 'that'll do' setting. And it works.
