Creating a visual concept of a character is a complicated process.
First you need to analyse your mind, go deep into your personality, thoughts, attitudes. Long story short, know how in fact he is because everything will influence his physical characteristics, the way his movements are, what he wears, the colors he uses, etc.
After that starts the sketches: scratch here, changes there, a little thinner, now a little taller, no no, a little shorter… until you have a final concept that will be used inside the game.
And now you can see a little about the evolution of our main character.
