what i would recommend, is pick the name of the character as a test, make sure it fits your world then do this, just to test it out.
“James walked into the …… and looked around the dark room, his eyes adjusted and he could see …..”
“Thor walked into the …….. and looked around the dark room, his eyes adjusted and he could see …….”
“Tiny walked into the …… and looked around the dark room, his eyes adjusted and he could see …….”
make it longer than what I did, but used this as a test to your character name, does the name you have in mind as you run the first parts of the story fit, does it have the feel that you want?
does “James” sound like the name of your character for what they are going to do, in the world they live in.
it might help you find the name that you want.
