What's the confusion here? If your race is too different from the character's the cosplay can look bad. For anime characters with ambiguous undefined features it might not matter as much, but for others it does. Skin tone also plays a big role. There's wiggle room, but if your skin is too dark or too white for the character it won't look good.
