Edene countdown

Just a sketch of a character of mine. She was to appear on a comic I'm still thinking on how to approach, but I never forget about her and her fellas.
- She was there, on the rooftop, knee firm on the floor, eyes closed, half of her mind lost in bitter memories, the other half, keeping track of a countdown. Any other bounty hunter could have used a stopwatch, or a remote detonator, but she wouldn't. She liked to occupy her mind, at least partially, on the mundane chore of counting. 15, 14, 13... The small explosive was to transform the reinforced window in a welcoming entrance for her, and she knew exactly at which second it could happen. 3, 2, 1... Time to work. -
