Ink & watercolor sketch.
The Society of Illustrators is my favorite place to do figure drawing because not only do they always have live music and a full bar, it’s the only place I’ve been to where the models wear some sort of costume. That means a lot to me because there’s only so many times I can ask my friends and family to pose, and they’re not models, so they twitch and fidget (sorry guys!) which disturbs the intricate, ephemeral folds of cloth, and then I have to erase everything and have an aspirin.
Photo reference books for artists fill in the gaps once in a while, but they’re too static, no substitute for a real person who knows how to sit perfectly still for up to twenty minutes. Always appreciate your models!
