While that one guy with the tall head was intentionally silly, I think I’m struggling most with proportions. I’m using a reference image for most of these, but none of the end results look much like the people in the photos. I’m also not using a grid as I’m doing this all with pen. I know I’ll eventually get it with practice, but is there anything specific I could try?
If faces are your thing, check out the Loomis method. It’s considered the essential method for consistency in head and face drawing. Also check out the Proko videos on eyes, nose, ears, etc.
Welcome to the rabbit hole.
Will do, thanks! :)
