I think there's too much going on here but I really like the funeral part. The top section seems to contradict the realism to me, though I'm by no means confident that others would agree with me.
If you keep the words on the bottom I think it should read "First...and last issue." Otherwise the focus is on "issue," for me at least.
first of all, your concept is AWESOME. I adore this as a setup.
As far as the execution is concerned, I think it needs to gel more. The upper part and the lower part for me seem sort of distant at the moment. I'd want the font to be somehow more comicky, I'm not sure how but I'd want it to leap out at me more, maybe like this? Or like this.
I also think the atom-energy ball thingies need better integration, maybe some motion lines to show them whizzing about or something. I'd like to see the funeral in the same colors as the upper part of the drawing. All in all it's a great start, keep workin' at it :)
I agree with what the rest of the community has suggested here. My initial read on it was confusion. since you are going with the comic book concept here, maybe break it up LIKE a comic book. I mean placing the imagery in boxes so it suggests different scenes. You can add a few more storyboards to tell the story. I think that would be a great way to communicate your concept.
thanks
