...then I thought this was the finished piece...
But, on further consideration, and in line with advice from Matt and Rup I think the piece needs to be treated more graphically. So I am currently working on an Illustrator version... I hope to enter that and post it here soon.
My basic concept was that the Brahma bottle was quite womanly shaped. Brazilian women are, I think, traditionally thought of as being quite sexy. I liked the juxtaposition, Hour-Glass Figure, Woman, Beer Bottle. I think the Brahma brand is quite cheeky. I had wanted a freer feel to my final piece, in the hope of capturing some Brazilian spirit. I just don't feel it's working for the brand.
