Four varieties of Beautiful. I applaud your divine talent to portray an already exotic race in several different lights, each one as stunning as the last, and yet profoundly unique. The cultural diversity in this alone is astounding. The brow ridges and what looks to me like different textures on top of skin tone, lend them each a forest-like quality. For example, the most distinct one for me is the bottom left; her skin is the colour of maple, and the way you've sculpted her features really adds to that 'wooden' feel. I appreciate the bejeebus out of this.
