I like 'D', but there needs to be more distinction between the light green and dark green areas.
Regarding the budget version I mentioned, how about some of these eyes? :
I think the last one pictured looks pretty close.
Or for a non-veined eye, how about this:
The rub is, these come in a maximum size of 28mm. If 28mm will fit Cyb's new sculpt, we will have a good budget Yoda eye option.
Here's a slightly bigger pic of the real eye you showed earlier Phil - it shows the brown, light green and dark green aread nicely.
It looks quite close to this, but I think the pupil is a little bit smaller on the real eye:
Will you be sending the pics of the real eyes to C&N too?
