So after looking at my 'final' design after a couple of days not looking at it, I decided I hated it and it looked simply awful.
I then went to research even MORE labels (ALLLLLL images from google).
It suddenly occured to me that I had in fact not researched competors and other sauce bottles. So I did so. The majority of these labels have a black background, which surprisingly works well. However, it looked really tacky within my designs.
