Congrats on the win. Color me very jealous. No doubt you will enjoy this item forever.
My personal bias is for Graig to create his paintings from B+W images. I feel like he really gets to bring the image to life by starting with a more blank canvas.
My favorite of the ones you posted, BY FAR, is the Aaron jumping at the fence. It is a spectacular image that would make an incredible painting, but probably not at 16x20. Unfortunately, I think it would need to be bigger to really get the full impact and majesty of that shot. From talking with Graig, it's my understanding that he feels 16x20 size is most appropriate for portrait type images. Even the one kneeling would probably look a bit better with a slightly vertically longer canvas to keep the full effect.
You might consider talking with Graig about different sizes and how much extra they would cost. I'm not sure if the extra cost is doable for you, but knowing whether what size is your absolute limit will help you decide on the best photo.
I would speak to Graig now about your ideas. He is full of ...great ides(bet you thought I was going to say something else

) and can help guide you through the process.
The good news is that no matter what you choose, you will love it.When I got mine, I posted this thread.
