My first take on the faces of Jason's team from He Who Fights With Monsters, up to ~book 4! I also just got done watching Arcane at the time soooo they're a bit more rendered than I usually do.
General: The native humans of Greenstone were described as tan/olive skin and brown/black hair, so that's Humphrey, Clive and Belinda. It seemed like the native elves were paler with brown/chestnut hair (Elspeth Arella, Dorgan, the Cavendishes) so I went with that for Neil.
Jason - how pointy his chin is became a big topic so I tried. His beard really does soften it up tho
Humphrey - Idk why I always imagined him with curly hair and possibly dimples. A bit Superman-ish, if you will. And also he's still like 17 so tried to keep him looking youthful despite the squareness.
Clive - He is my favorite and I love him. I gave him slightly darker skintone than the other Greenstone humans because he's from the Delta. I keep drawing him with longer-ish hair slicked back so when he gets frazzled it can be more of a mess lol
Sophie - The Celestine is described as having chocolate skin and silver hair/eyes. Tried to give her that defiant expression.
Belinda - Couldn't find as many descriptors - but scraggly/curly hair and cute next to Sophie's beauty.
Neil - Couldn't find more description than the fact he was a bit too stocky/muscular for a typical elf and had his ear points hidden by hair. And that he acts vaguely more Jason-like as book 3 went on
