Drawing from a photo is easier than trying to do a live bird; I can study it often and return to finish it when I can see if I missed a detail. I noticed the empty spaces around the bird remembering Liz's Saturday afternoon Zoom class that I took. I wouldn't have paid attention to the space around the warbler, if not drawing it. The space around the main focus will help me with the proportions of the nature scene, such as the size of legs compared to the body or size of the head versus the body.
