I think your drawing skills are really solid, so there's not much to say there
You've got a really nice calm color palette, but I think its lacking a bit in contrast. Nothing really stands out against the
background. The aliens blend in with the buildings, which I guess is good for them so they don't get shot so easily, but it makes it harder for us cause we want to see whats going on
I think the new page layout for pg 3 works a lot better. With the old layout, I thought the humans were on a different building, but then I looked back and saw them on the right side of the roof in that first shot. Its kinda hard to see them cause your eyes aren't drawn over there. Maybe if you had one of them yelling out an order or something?
When the guy says "I'm flanking!" I'm not really sure what happens. Did he move to a different spot? It also looks like he's yelling to guy off to the left, but I don't think there's anyone there based on the establishing shot.
The next bit of dialogue is also kinda hard to understand because of the placement. I read "he'll be hear! cover now!" first, then, "where's clever?" Another thing that made me have to stop and think was that cover and clever look so similar, so I first read it as "where's cover?" This is the readers first time seeing the name Clever, and it didn't really click for me.
Because these guys all look exactly the same its hard to tell who is who. For example on page 2, when the guy presses the button on the card in panel 2, is that the same guy as panel 1? The camera jumps around quite a bit and so does the lighting so its hard to tell if these shots are all the same dude, or different dudes. The stuff behind the guy holding the RPG is dramatically different from the stuff behind the guy who pulls out the card in panel 2.
Hope that all makes sense.
That cover page is awesome by the way. Very cool idea.
