YEEEEEEEEESSSSS. It took me FOREVA to find this comic again, cause, you know, I didn't have an account, so I saw the first part and then BAM!- I forgot the title. Thank you God that you put something up in the voodoo section or I would have never found this.
It's all drawn in pencil, then scanned. Most of the lighting is done in Photoshop - not with use of filters, though. I mostly just use regular soft round and hard round brushes, and a couple of different texture brushes I made.
