When it comes to writing out the story and making concept art of a game, have you ever had an issue or some kind of idea block where you got an idea for a character by having the name, personality and type of weapons or fighting style figured out, but you can't seem to figure out what their appearance design can be?

I'm having one of those moments and want to hear how you managed to overcome a tricky solution as I'm not the greatest at drawing but I would like to hear your experiences.
