I'm still keeping things loose at this stage of the game. It's time to dress up the character in an outfit and give him the features that indicate his personality, profession, etc.. This guy's going to be a gladiator-type character, so I want him to have armor -- but not TOO much armor. Remember, an outfit has to be functional. In combat, the character needs the freedom to move his body. This design is based loosely on a Roman gladiator armor, with heavy plating on one side of the body and lighter armor on the other. It's always a good idea to get reference material when designing a character. For a warrior like this, look into history and experiment with different garb from different cultures and time periods. Doing the reference work will help add a level of realism to your character.
Make sure your armor shapes rest above the muscle layer. For this example, I gave him a bit of an organic armor, fashioned from animal shell or hide. The belt and boots are metallic, so I want those pieces to be a bit more angular and have straighter lines than the gauntlets and battle apron. Toss a weapon on the guy's back, but make sure it's not just floating there. That's what the strap is for.
I'm just roughly indicating a hairstyle and facial hair for this guy. He's going to be around 40 years old -- a battle-hardened warrior. The beard and moustache will give him somewhat of an Oriental, Ghengis Khan feel.
