Miniature portrait-silverpoint on parchment 2"X3"

"Beau" in silverpoint with added watercolour

This portrait of equine author Tena Bastian's stallion Beau (@TenaBastian or www.tenabastian.com) was completed from a photo that Tena sent me. I altered the background to improve lines in the composition but did my best to capture a likeness of Beau.  This is tough to do from one photo but Tena had other photos of Beau on her website and that helped as well. It's about 8" X  12" with 6 layers of silverpoint ground on stretched 140lb arches hot pressed paper. I've included a picture before and after adding colour to the silverpoint. I'd love to hear any opinions on the addition of colour to the picture.
