WAY too mcuh light.
Go get a cheap clamp lamp and the SMALLEST CFL you can find, and stick your dome under that, in a spare closet or something- keep the light about a foot or 2 away.
Cloning is as simple as chop it, plop it in cloning goo, and stick it under a CLEAN dome in DIM light. Once you get it, whcih is going to be very soon, it will become second nature for you.

Also those cuts are really tiny- are you getting a tip, a fan, and a lower node which is then stripped-n-dipped?
