DIGITAL COLOURING HELP NEEDED FOR OTHERWISE-FINISHED PROJECT

You should definitely try to offer something game design-related in return, such as maps, coding, etc.

Sounds fun, I might in my spare time do it. But, you know, it really depends on how many portraits and stuff. So, I offer to do it just for fun - however take conscience that I might take longer than expected, as I rely on school's PC to do stuff. Is it allright with you? :]
