I'm gonna try, I think I know which preset. Not promising anything.
Unfortunately, there aren't a lot of options with green eyes on any of the faces. Face 4 has 3 relatively bright green eyes and one sort of pale slate green eye, but the expression looks very defiant/sassy, and the eyebrows are rather ridiculous. The serene, relatively neutral expression on this face from Perfect World is hard to achieve on a Castanic. The skin color will also either be much more pink, or with a gold overtone.
If you are dead set on the Castanic race, you may be better off disregarding the template, choosing a face you like the default of, and adjusting from there. If what you want most is the green eyes/red hair combo (one of my favorites as well), you should be able to create it with either a high elf or a human.
Yeah I'm not so attached to the green eyes as much as the dark eye makeup n short red hair. I really love castanic armor the best which is why I'm hoping for closeish as castanic but I know it'll be easier on elf :( Was just sort of hoping someone would see something in one of the faces that I didn't n come up with something. Appreciate the responses though ^^
