Sounded like fun to draw. Here's my initial character design:
I can be a stickler for panel continuity so I wanted to layout Green's tatoos before I got to drawing him in the actual comic pages and keep it as consistent as possible.I drew the above intricate image with the idea of scanning it at a high resolution and simply using photoshop to place it over the inked drawings of Green. I gave it a try once, but the warping/shaping and cutting it took to make it fit from various angles was more effort than it was worth and I ended up losing time.
Since I would be drawing each tatoo by hand, I wanted a simpler but still detailed tatoo layout; both because I would be drawing it over and over again and because I didn't want the face looking too cluttered when rendering the tatoo in ink. The above version has less leaves but, I think, a bolder design overall. Most of the leaves and sections divided into prongs of 3, so it should be easier to draw without having to count how many prongs were on each leaf every time.
I ended up adding more leaves surrounding the face/design, but the main structure is still there on the page. You can see I done something similar with the chest/arms to give the tatoo a consistent focal point and the 'in-between' parts will be filled with leaves. Now that it scanned, and in my Slaughterman's Creed 'tools' folder, I just open the file for reference when drawing Mr. Green.
If anyone is going to BICS next week, I'll be carrying about a few pages of Slaughterman's Creed if you'd like a closer inspection.
