**Unicornst..your right - the instructions were too complex for me so I downloaded your eyes (many thanks) and they're a big improvement except that the pupil doesn't seem to have a highlight...but that could be something to do with my renders. 

Someone over at DAZ suggested  AdoranaEyes 2 here in the freebie section so I'll check that out tomorrow.  All this just to get V4's eyes to match the realism of the rest of her body! Phew....**
