think i'd lose the yellow glow comin up from the lower left though in batmans panel
it helps to define that 5th panel there but i'd tone it down. its kinda distracting. like its trying to be its own panel. those last two have a pretty strong glowing lightsource coming in so it almost looks like its trying to fit in there
wow the clouds in the Bg, its a really good add to the colors. i love it but i not sure about the blue stroke in batman. looks like some kind of force field or something. for the rest, i think its one of your best works.
