I actually really like the blue! Nala's family genes don't seem to be very strong in her kids, as they seem to take after their grandparents on their dad's side. So maybe this would be a nice switch up. Have you tried him with Sarafina's green? Or is it too similar to Nala?
Erm, I like Mega's colors but orange are nice too. Personally I am a fan of Mufasa's and Nala's eyes just because I don't like Kopa's book design (Simba's clone) But your Kopa is quite different as it is.
Forgive my lack of skills in knowing how to add thumbs to polls.
I really really like him with red/orange eyes, but I'm unsure if I should change it. I dont particularly like him with green eyes anymore :/
I only care enough to keep the green eyes because I enjoy him being different from Simba, buuut I think he looks different enough without the green eyes, and orange/red looks REALLY good with his current colours. So I dunno what to do.
