holy shit! you keep proving to me that you're the best ever on here...
nothing wrong with it to be honest, just one tiny lil thing, some parts of the text are blocked...i dont usually see that in real movie posters..
Just one quick thing. Whered you get the tripods at?
well u still need text as in the name of actors and that stuff
also try maniping the guy because he looks unusually clean, add dirt on his hands and shirts and maybe get the shirt torn.
also add little people far away running from the tripods
Extra comment..
Why not try other color rather than always using "rust/brown" as the main color filter of your poster? Maybe blue? just for a change as this filter color has been used over and over again imo.
I thing the space shuttle at the top needs some orientation adjustment as it doesnt look well positioned imo.
Other than that, and the stuff TDK and Alhajri mentioned, i think its all good.
