Learning to observe shadows and light is quite the skill! I definitely see how it helps bringing three dimension to the images. It is hard to combine the dark and light colors at the same time. I am enjoying practicing and learning in the process.
1. I like drawing from a photo because I have time to pay attention to the details. I can redo something if I feel it doesn't quite lol like the photo I have plenty of time to make mistakes and to try to improve the picture. It was easy but I don't give much detail not adding colors. 2. When I drew the bird i did notice the different kind of textures of the feathers that i might not have noticed, I also noticed the lichens on the branch and the ring around the bird's eye. I think when nature journaling I will be able to pay attention to details that otherwise I would overlook. Just looking at a picture of a bird I get the general idea but don't pay attention to those details as much.
