Those are some great shots! The same tree over time would be very cool thing to see, maybe for next year. It doesn't surprise me that so few people are out that early, it's the same here. People want to sleep in! I love early mornings though, always so quiet compared to the noise of the day time.
I really like that second to the last shot, that one was perfect!
That is a cool idea to the same tree through the seasons
I have been an early riser since my teens a habit I just can't break
