I started with some sketches of the face to explore some battle wounds and beards. It kinda looks like Captain America and Orlando Bloom haha. The clothes he wears has to be of the year 2070 more cyberpunk style.
The devil on his shoulder, I prefer him to be more like a little vampire instead of a monkey.
His last power, will be completely possesed by this little individual, so it will have the same appearance but in a more threatening way. I also have in mind that there will be a berserker transformation where the demon has total control and becomes a monster, but our hero eventually gains control for a final transformation with all the demonic powers to the fullest.
