His face is hard to get right for some reason. Francis has a slim, oval face, with a jaw that isn’t too defined and getting that across in my semi-realistic style is often a very fine line between styalization and glaring anatomy error.
I often end up crossing over into anatomy error territory and need to redraw his face a few times to get it right.
Half of it is probably my perfectionist issues nitpicking tbh because I’m used to drawing more realistically and my attempts at styalization tend to stand out to me as anatomy errors.
Edit: his uniform is also a pain (as much as I love to look at 1800’s RN uniforms it does verge on what I consider complicated). I’ve only recently figured out how to simplify it though I couldn’t simplify it a whole lot without loosing historical accuracy. I also have trouble visualising how the cravats work.
