i have a oc challenge if you have a sibling mix them with you if you don't have a sibling use a friend if you have multiple siblings choose one(i chose my twin sis) for the face do a sort of mix between you and you persons face. for the hair if you have short hair and your person has long hair do medium hair(vice versa) if you have the same length do that length. for hair style do a mix,like if you have curly hair and the other person has straight hair make it have some curls but also have it be straight. for hair color do either a mix of your hair colors of whatever is in between the hair colors. for the clothing choose something you both like and make that what they wear. for the clothing color either mix your favourite colors or use whatever color is in between your favourite colors. for eyes if you have the same eye color use that color,if you don't either mix the colors or do a heterochromatic character(different eye color on each eye),your could also just choose the color in between. for skin tone just do whatever is in between your skin tones mix your names together for the oc name for height if your the same height use that height but otherwise use whatever is in between.
