The biggest challenge was using the photo she gave me! This is something I swore off ages ago---unless I was able to collect my own image by drawing from life, or shooting my own photo, I'd refuse to do any painting commissions. That's usually part of my inspiration---the composition of light, shadow, color, all directed by me to create the final image. I was open to something new to push my creativity though, and decided to work with what I was given to see if I could succeed with something that made the both of us happy.
First off, here's what the original 3 x 3 1/2" photo looked like:

This is the initial sketch on the 12x12" canvas:

This is about 3/4 finished---if not almost finished:

Here's the finished painting, after it was checked out & approved by the new owner:

With this painting I've learned to not obsess over exactness & to be satisfied with "close enough". Knowing that my buyer is thrilled and very excited with the finished product makes me happy too!
