Do you take book characters as well?
Lord Alden Virgil Ewart, Viscount of Gravesend and Baron of Allhallows. (But really he just wants to be called Alden). Paralogical expert, researcher of the occult and begrudgingly a spiritual medium/mindreader.
Age: 20, but he is often confused for somewhere between 15-18.
Build: small, rather fragile, only 1m62 tall (5' 4")
Hair: ashen brown colour, generally kept nicely, but it's been a while since he's seen a barber so it has gotten a bit too long
Eyes: sharp and piercing, intimidating even. An icy light blue. He wears glasses.
Ross Finnleigh Forrest. Blacksmith that dabbles in mechanical engineering and tinkering.
Build: tall, broad and in good shape due to his job as a blacksmith. He's 1m89 (6'3").
Hair: coppery brown, kept short and practical for his job. He can grow a beard, but it alternates between short and clean shaven (this is up to whichever you prefer to draw him with).
Eyes: Dark green, and he often has a very playful/confident expression. He also has a few freckles over his nose and cheeks, depending on whether or not you want to draw those.
The time period in which both characters are set is Victorian, so they wear time appropriate clothes. Alden often wears very neat and clean clothing, including suits/other clothes befitting a British Lord.
Ross really doesn't care much about looking decent, so he only buttons the buttons absolutely necessary. If he tries his best he may dig up a waistcoat from somewhere, but that's a big if. There's often smudges of grime on his clothes/hands/face, due to his job.
I hope this is enough description to work with
