SEN SEN THE CRYSTAL MASTER GUY BOY PERSON
11 year old boy and crystals are what you need to focus on when deciding on the colours
what kind of attitude does he have, what environment/age is it set in?
first thought would be a blue, gold and brown colour scheme
the gold and brown can be interchangable with hair and clothes depending on your preferences.
-blue crystals, brown suit, blonde hair, azure blue eyes, like brighter than normal, to match the crystals and create the link or bond between the crystal king and sen sen.
-blonde hair makes him look a bit more innocent and 11 year oldish, also contrasts nicely with the eyes and crystal helmet
-or brown hair if he's a mischievious naughty little shit who argues with the crystal king all the time, also makes the blue eyes stand out more, making the visual bond stronger.
-then brown or gold cloak, depending on what you use for the hair.
gold makes it seem more royal, matching up with the crystal king and makes him look like a naughty prince
brown looks a little rugged, like he works hard and wants to help people
