UPDATED Justice league poster

It's cool, but I would change the lighting, the title, and make them look less like Action Figures.

Good concept, but the execution is still poor. I'm not entirely blaming you, though, since I know such a concept is not an easy thing to be finely crafted. Well, first off, the font. I hate how people frequently use the Justice League animated series title card for their movie posters, perhaps thinking that it will be used in the real movie, when it's actually just a lazy, and uninspiring move. Of course, the best solution for this is to be creative and modify a certain type of font yourself, but for your poster, I recommend you to remove the title, and just put a "Coming Soon," or something else, instead - the concept fits better for a teaser poster, than a full-fledged theatrical poster.

Secondly, the globe. Would you expect for a planet that is bombarded with large explosions all around it to stay so vibrant, calm-looking, and for Earth's case, still so blue and green? Yep, not. And it does have an effect on the scale, which, like SuperDude001 said above, doesn't make it seem like a massive superhero sci-fi movie. You can add a little bit of flares here and there (it wouldn't hurt, really), adjust the colors, et cetera.

And it also affects to the lighting, as a whole. logically speaking, the interior of the Watchtower will also be showered with the blazes from the explosions, thus it won't stay so "clean." My suggestion is to dim the lights on the interior (and the heroes), and whip up some yellow/orange shadings onto them. That way, the whole layout of the poster must blend together, and also will create a more dramatic effect, overall. Also, are you putting the action figures there just as placeholders? If not, then the lighting on them should also be made more subtle.

Those are the major flaws, I think. A couple of other details here and there, but those three are the most prominent ones that you have to fix beforehand. Once again, it's a good concept, but for every good atmospherical poster concept, there also comes a tricky execution. It's a great thing to see someone coming up with such an idea, though, so keep up the good work.

i went with the dark knight/man of steel font

Very nice man! Brainiac can use a little ore editing though.

Well the others have said what needed to be said, so all I'll say is: nice job.
