I don't usually do this, but as I think you're art is pretty damn close to being there, I've rejigged it to show where I think you can give more room for the letterer/writer/editor to breath a bit. I'm glad to see a bunch of balloon placements in the pencils, but I don't think you've been generous enough with the space - the old 2000ad 10 commandments have a couple of guidelines for balloon/dialogue/caption placement - leave 25% of the top of every panel free and character speaking order is always left to right.

Panel 1: I've shifted the action over to the right a bit, this gives room for any captions required and doesn't take away anything from what's happening. Your eye reads left to right, and the space from Dredd's feet to the panel border was pretty much dead space - not contributing anything to the story telling. (BTW Nice sound effects!)
Panel 2: I've moved everything down again - cropping dredd a bit more heavily - normally not a great idea, but here it adds to the claustrophobia and gives more room for dialogue.
Panel 3: I've shifted Dredd down and a bit to the right - the aim here is to take the dialogue away from the bottom of the panel and shift it to the top - I prefer my dialogue above the art - read story then look at picture. How it's done in my house

Panel 4: No chance (though you could stand to move the gun further from the ship to give more lettering room) If I were lettering this, I'd want to have a LARGE balloon and teeny tiny text, which I don't think there's room to do here - making a balloon big enough for dialogue alone isn't enough - sometimes the balloon will be larger than you'd think.
Panel 5: No change, though I don't like balloon placement on the guy. I'd probably have made panels 4 and 6 a bit thinner to give panel 5 a bit more room - more dialogue means larger panel.
Panel 6 - moved gun down a bit, giving more room for dialogue.
As I say, I don't normally micro suggest like this, but this is the sort of lettering pass I've often done on my own pages, keeping the art as intact as possible but giving letterers room to do their thing. Which is why I'm called LL Cool PJ*.
