atoms, not atom bombs.

What is that?
All in all I found the poem to be really bad. "he won the game" is not something you'd hear in an epic, it generally seems to go by the gamer definition of "epic" which is just calling something epic because you can't be bothered to examine or describe it. It reminds me of Edgar A. Poe and his "draw the rest of the owl" style. "It was so foreboding and beyond human imagination". Show, don't tell.
It breathed fire, it was so heroic and resolute and a lot of other adjectives just floating about, there is no fight at all - that all is skipped, the army faltered (because fire was breathed on atomic bombs? okay?)... it's just a bunch of filler text with no substance, I can't imagine any sequence of events based on this.
And one of the images shows several people riding on the hippo, with another hippo in the background, totally failing the assignment. None of them show atomic bombs on legs, and don't even attempt to depict a speck of dust.
