Practice Makes Practice
When it comes to reproductions, I aim for capturing as much of the original as I can.  Here are both the original Mornin' Sunshine and the first reproduction on canvas.

I am working with them together touching up the original while putting the next layer on #1. When they are in balance with each other, the original goes to its new home and #2 is started.I then repeat the process until balance is achieved and then #1 goes to its home. Then #3 and so on ...

Over time, there will be mutations and each new one in the edition will have unique qualities and changes. This process is often referred to as an enhanced giclee.
