Ok so he finally shed last night

Got up at about 3am because I couldnt sleep, had a little peek and I saw the shed hehe.
Yesterday
Perfect shed

I think o.O. Just to clear things up a little cos im a bit confused about the shedding problems to do with the eyes. How do you tell if a bit is left over? Is it just the scales around the eye, or there a peice from over the actual eye that gets shed too?
Another quick question, after each shed, do they tend to get lighter in colour, or can they sometimes get darker too? So anyway, here he is now
