Stellar work! Honestly think it's a creative and worthy display of the more artistic side of Newgrounds Movies- a side that I believe needs to be expanded.
Manipulating the silhouettes to reflect the light sources is both brilliant and effective, as well as making everything simplistic yet aesthetically pleasing.
You could definitely assume a deeper meaning from the short as it would seem that this tells a story of the discovery of fire and of those who discovered it. It would seem as though the blue could represent the curious innovators of society but the white the greedy and selfish thieves.
I can agree with juersh's critique. My one critique (more suggestion, if I may) would be to revisit this project later-on, see what you can do to improve upon it with the experience you will have gained.
