Poster First Draft

This is the first draft of one of my posters. I am really happy with the effects I have got going on in it. However there are several ways i plan to improve it before it is complete. Firstly I have had the idea of changing it to portrait A4 and then adding a mirrored world image in A4 to make an A3 spread poster. I think this will give me a great effect that will look professional in any media publication.
