This is a tricky one but I'm leaning towards the killer enchi as well. I was shocked to see how similar pastel enchi and super pastel enchi are when I was trying to ID my pastel enchi. I thought he may of been a killer enchi as well but he doesn't have quite as much head blushing as yours. That's why I decided pastel enchi for mine but I think yours is right there to say super pastel enchi. He really is gorgeous either way ;)
