When SSG brought tieflings to DDO, I know I, for one, asked to have just a few small horn, and normal eye options for those tieflings that are born looking closer to their humanoid parent and are better able to disguise their nature. I recall being told WotC signed off only on 5E tieflings... my interpretation being with horns from the wildebeests of Africa, the kind that absolutely would damage if not kill their mother on the way out.
So imagine my surprise, and pleasure seeing the new movie Honor Among Thieves with a tiefling main character that met my desires for a tiefling character e.g. more human-like with normal eyes, small horns, and more readily able to disguise herself as human with just a hood.
1. Small horns off the side of the head rather than planted squarely on the forehead. Closest approximation in DDO horns are 36/37 but they still emerge from the forehead making the forehead not smooth but looking like a pair of buttocks.
2. Normal smooth forehead, absolutely not possible with DDO tieflings.
3. Eyebrows, absolutely not possible with DDO tieflings.
4. Natural eyes with pupils and irises, not possible with DDO tieflings.
This is my request, yet again, for DDO to add at least 4 options to tiefling of small, easily hidden horns with a smooth forehead and eyebrows, and 4 options of normal eyes... the eye color selector could still remain it would just color the irises. They could reuse some of the eye options from Aasimar.
