Here's a sneak peek of a commission I had recently. It's the biggest illustration I've done to date (1.8 x 1m) and it was a quick turn around.
The client made me alter the expression from this, to be more engaging, and it turned out well but I do prefer it this way.
I was a bit freaked out about the level of detail I would have to include at this size, but it turned out not to be too big of a deal. I'll post the full image once the client gives me the go ahead.
