Bragging rights: On the marker study and the final, the heavy black brushwork was done first, with no pencil sketch, then the micron line-work and color added. It seems counter-intuitive, sketching with a brush, but that's what makes it so badass. haha.
Line-work first? Psshh... Don't worry, daddy's got you.
P.S.- yes, that's a bandaid on my thumb. I survived. :)
