1. I did not mind drawing from a photo at all. Especially a bird as they never sit still. 2. The excitement of drawing a warbler was the easiest part. I love warblers. The wings were a challenge for me. 3. Um, everything about the bird. If it was moving I'd be lost. 4. Probably. It's hard enough ID'ing birds let alone trying to draw one on the spot. Maybe once I start learning how to draw birds better it will come easy but right now a photo works for me.
