The Last Hope in a World of Darkness [original]

Description:

In a distant future, the world has been destroyed by Humans in a Radioactive War. The sky is painted grey from the smoke. There is no light and everything is bitch black. Suddenly, a Butterfly emerges from its cocoon, it's wings glowing a vibrant blue. The radiation must have affected it. A cat notices the butterfly and goes up to it, depressed since he lost his family in the darkness surrounding the two creatures. ((This is hand drawn, I'm posting another one with better glowing effects. Kinda))
