it was easier drawing from the photo because I got to study the subject. depicting the feathers on the bird and depicting the details on the branches was difficult. there were lots of things I wouldn't have noticed if I didn't have to draw it - the shading aroud the bird's head, the dappling on the branches, the depth of field between the leaves on the right and the leaves on the left resulting in different sized leaves. Yes, this would make a difference in nature journaling.
