Colour scheme was developed by Poh-Ling, my partner, and we're currently in the process of colouring all 9 sequences. The program we've used is
Photoshop (mainly version CS2). We officially have 4 sequences remaining, and have since done some test renders to check out various settings and visual effects for the final export.
Here's some samples from the movie:
Sequence 6 Scene 5 ~ Wolf and Sam
Sequence 8 Scene 4 ~ Wezz in action
Sequence 8 Scene 5 ~ Showdown
