Our first response to the prompt, Allisonn, and what a wonderful drawing! Your are way too hard on yourself. I think your drawing is very similar to the bird in the photograph. Not perfect, but very close.
Besides your drawing, I love the story of your grandfather and your relationship with him. I was smiling as I read your words. My paternal and maternal grandfathers were deceased when I was born, so I gravitate toward stories of granddaughters and grandfathers, wishing one could be my story. Thank you for introducing us to your granddad.
