First of all, there are no set farstrider tattoos on any characters really. What Rommath has are runic tattoos, probably more for him being a mage and not a ranger.
If you refer more to Alleria’s tattoo. I personally find them rather dreadful and not really fitting of the blood elves right now.
No red eyes, blood elves aren’t undead. Making an undead option just for rangers wouldn’t make senses at all.
For DK’s thought it would be cool to have a red eye option, would make more sense for them to have them.
Everything else you mentioned is nice, more scarring would be cool. Some other hair accessories would be nice too aside from the tiara, doesn’t really fit my paladin.
