The original portrait was created in 1636 by the artist Justus Sustermans. Galileo was 72 years old at the time. He had already stood trial for his scientific writings and beliefs and was living under house arrest until his death a few years later.
Even though Galileo's nose looks like it was in a bar fight in my vector portrait and doesn't capture his age in the way of the original portrait, I have learned more about using Google Drawing for Vector Portraits.
Lessons Learned on this Attempt:
1) It is much easier to do a vector portrait with the original image beside the Drawing rather than tracing on top.
I placed the original portrait on the left. Using the Polyline tool within Google Drawing, I traced the shapes on the original image and then dragged it over to my canvas on the right. This made it much easier to match the colors and fill the shapes. It also provided valuable feedback along the way, even though it couldn't save his nose!
I look forward to further refining my skills using this technique. The act of creation is a great stress reliever and a means to focus energies towards something that I find incredibly relaxing.
