HI there!
I personally am not based in Nigeria, but I do know someone who is. We could co-ordinate, and work for this project of yours, since I feel I'm pretty good with manga line art and the like. I work in both digital and traditional mediums, and it is up to your preferences which medium you'd want. It would be nice working on the story together as well, since I'm pretty good at script-writing, so I could help with editing and dialogues too.
