I was looking around the web for a custom or unique glass bottle I could use for a concept student piece (a vodka bottle/branding) that I want to include in my portfolio. When presenting the assessment I used a glass Antipodes water bottle. Knowing it was just a mockup, my lecturer didn't care. Although it is very unique and cool bottle, I feel as though it is really obvious it is a water bottle and an existing brand.
Just wondering how other people have gone about this, when presenting a concept piece in their portfolio? Is it a big deal that the bottle is from an existing brand? Or because I am a student and this is not a client piece, will this be overlooked? I don't want to be accused of stealing when presenting my work haha
