Good idea that reminds me of our project in its relation to Environment. I showed it to my team members 2 weeks ago, but they were not as inspired as I was after they saw it.
The idea in my opinion is not only eye-pleasing but also metaphorical. It transforms something we consider harmful to our landscape into the landscape itself. There is a dose of sarcasm, as it is the opposite of what we expect (what pollutes our nature has replaced it), however the outcome is beautiful and thought-provoking.
I find it fascinating how something discarded could be brought to life only through a photograph. Plastic bags have a range of colours, they are flexible and could be used as a material, just like used paper waiting to be recycled or food/furniture packaging.
