Penultimate Shadow Character Line-Up

A Character Line-up for a personal webcomic I plan on making.

Penultimate Shadow is about an optimistic young boy and his two friends who struggle to survive in a post-apocalyptic world overrun with shadows. At day, the shadows are incorporeal entities bound to two-dimensional planes but at night, they become three-dimensional, corporeal monsters whom actively seek out and attack humans. Along the way, the three teens meet other survivors and must face difficult decisions, questioning their own beliefs and themselves.
