Angel - anime like, obviously blue, in your face (good for distance shots)
Nudy - subtle, natural but may also fade into actual eye color *unless you have a light eye color*, good for close ups
Olive - Not so sure, haven't heard any good feedback about this series
Are you using super angel/nudy or regular angel/nudy?
Because...that would make a world of diff.
If regular, I'd suggest angel so your eye color shows up each time. But if you're using super versions, I'd say go for super nudy. I prefer a cutesy/innocent shine to Ciel cosplays anyway.
An innocent shine to the eyes...balanced by a frown and being bratty/meanie face. XD What a juxtaposition.
And kudos for you on getting the contract eye. D: That looks MIGHTY expensive.
