Keeping on trying to make eyes

This would be my third attempt to make a pair of eyes. I'm still trying to figure how to get around the issue with Dwayna in her eye being so small... Perhaps I should tiny the pic back into one large eye instead of two? Or skip the iris and put Dwayna in all of her eyewhite instead...

I'm getting a bit flustered with not being able to make any good realistic eyes...
