Here is a sped up clip of my process from a recent commission. Not as loose of a technique as I was hoping to achieve, but doing portraits for people is a tricky thing. You want the client to be satisfied with the likeness, while a more expressive approach I've been pushing towards can compromise that. Did A LOT of warm ups before jumping into it, but still had some large-scale illustration board anxiety.
At the end, it turned out okay, and it made for a great anniversary gift :)
