I would never ever presume to tell anybody how to layout thier poster. I submit this image only as an example of what I might do given the imagry on your poster. You aksed so I am giving my input. Keep in mind I am a hack and know next to nothing about anything. Easpecialy graphic layout
Please feel free to think it sucks and call me a retard. I probably deserve it. Mostly because I hate when people post shit like I am posting now.
