Outside SB's contribution everything else is pretty bad. I love Laz's Jean/Xavier poster best though and has been the only contribution here that's really good along with SB's logo.
Laz,
I know you said you are doing these at work but you need to be mindful of not rushing anything. The bridge and cars look blurred and very badly positioned. You need to skew them correctly and also get rid of the blur. Since this is Magneto tossing around cars I would have gone with a "sonic" filter so that the vehicles appear to be moved around by magnetic force. Also The mutants are positioned in the wrong places, example, you should have pushed and scaled Magneto down some. That way it gives the illusion he is throwing the cars around. The way he's positioned now doesn't reallly flow because the cars are scaled odlly forward and doesn't give the presence that he's tossing them around.
The Bridge looks unleveled by the position of the mutants. I'm going to assume you wanted a "bending" bridge. It could work if you sharpened the images and used a higher res. I would also watch the contrast on the images. All the colors don't blend in correctly. Be mindful of the saturation levels they all have to match accordingly.
Mystique and Pryo's appearance doesn't match up with Magneto's. Use different poses or images.
All your images need sharpening. Don't forget to do that when working with stills. Whenever you scale an object often they blur by default. Sharpening once usually alleviates that problem. Again check the positioning of your mutants. They should be suited well together.
Also the Logo is a mismatched. Doesn't blend in at all. You can have an odd logo or a "stand out" logo but it also has to match color hues within the poster.
PS. Use lighting techniques to rid the shadows on the mutants. It's very odd for Pyro to have a shadow on his face if he's outside. Same goes for Mysty and Mags.
