Here’s a recent assignment with the photo ref included. It required that we draw Ron from a 2-pt perspective (from a side angle, level with his head), Sophie from a 2-pt vertical perspective (basically, looking down or looking up at her) & Francis in 3-pt perspective (either looking down or up at him, from a side angle).
I’m pretty happy with the results. I think I got a little too excited over the guys ears… they could maybe use some toning down. I could have caught a better likeness of Sophie but I am happy that at least she doesn’t look creepy – way too often babies look freaky when they’re drawn since the proportions are so easy to get wrong.
