This is wonderful just as a piece of art, with its great composition and colours, but when I applied the political symbolism it became even greater. It is really interesting as a subject itself, and the way you illustrated is really effective.
It's amazing the way some drawing can trigger the right ideas. In fact, as a random advise, If you want to become an illustrator, you have to master THAT above all. Not saying I've mastered anything, though.
