I don’t think that I agree with the above comment. Not that they are wrong, but personally I like the way it is composed. It has a mixed feeling of solitude and desolation, which is vastly due to the simplicity. The character is alone at their post in the middle of a war, about to have his morning… tea? I don’t really know if it needs the ruins in the background. I guess it all depends on the feeling that you are going for, if you are just composing a cool scene, then maybe you could add to it, but if you are trying to sell the story above, then not so much.
