Oil spill photo manipulation

The project theme was "Futures" and I though about all the world problems and how the world could look like if we carried on doing these things. I wanted to make a poster type look to grab the audience’s attention and make them think of all the dangerous things we are doing to the world.  If I could change anything I would try and crop the image as the negative space looks odd where as if it was more compact it would look more professional and eye catching.
