Progress of an Eye - From Base Tones to Detail

Thought this would be interesting to look at. Some times I think something is way further along than it is. So, I took 'before' and 'after' pictures (with a camera better than my iPhone's) to see how much an area of a drawing can change in a short amount of time.

I hope you find it interesting too.
