I tried adding color to the sculpt model using vertex painting. Having color definitely makes it much easier to imagine the final look.
The colors are just a temporary paint job, so the design may change.
I'm also thinking about adding tattoos. For AO, I went with a very ethnic-inspired tattoo design, so this time I'm considering using tribal tattoos instead. I haven't come up with the design at all yet though lol.
The facial expression may look a bit goofy, but it's easier to create facial animation when the model starts with a neutral expression, so I'm proceeding with the modeling this way.
Right now, since it's still an anatomy model, each part is separated at the joints. From here, I'll merge everything together and make the final sculpting adjustments.
