Alright. Well.
Okay. First of all. Nice job. You've massively improved art-wise from your previous submissions. This is most likely why you were off for some time; to improve.
It's music crechendos at ideal points and adds to the climactic and action filled stylé of the flash. And the story? I'm guessing a bit of a fruit smoothie of Crystal Skull theory and the mayans. Hell. Even with the traps I was pretty amazed how intense and complex they were put together. Even if they had no historical basis.
Overall. Nice job. I hope to be seeing more of this kind of effort on NG submissions in the future. 'Cause frankly. You've set a new mark.
