I think characters shoot look like their stats, and battles! Maybe a lvl 50 with lots of STR would be like totally strong, and a lvl 1 with 0 STR is like skinny and small

Maybe after each series of quests is completed, you get a cool hair style or even look. maybe your body is like covered in tatoos for one, or maybe you have like super long hair after another... idk.. i want longer hair!
