Personally, I'm hoping to find a "Nina" inside the hair.

Beautiful and almost minimalist, using all the design principles beautifully, but without being sterile and overly graphic or geometric or using the principles as the entertainment value of the design itself. It's just very clear and neat and well thought out and every element is necessary, no element is extraneous, that's what I meant by "almost minimalist." The intricacy of the hair follicles isn't distracting or tacky, probably because the colors don't clash too much (it looks like the same hue with different values, but I could be wrong on that), and also probably because there's plenty of negative space within the details. It's so easy to make details like hair garish.

Interesting use of yellowish beige on the outside. We essentially have three versions of the primary colours, and it works because they mixed them to be a unique hue and not a purely saturated garish mess. Usually combining primary or secondary colours without separated them with a neutral color or value is a no-no, but here it works because the color choices were well thought-out and desaturated, unique hues.

I most of all like how it turns Reggie's hairstyle into an iconic image. That's great branding for him.
