That second photo works really fine for me, with the footprints in the sand leading the eye all through the photos, which is rare in so far as it is a landscape, yet taken in portrait style (upright pictures), a trait to all you landscape photos presented here, and an interesting one, I must say!
If I had seen the sight that you captured in Photo 3, I would have tried my hands at that, too. I just love backlit flowers! With the setting sun, the colours become even more intense and the light from behind is no longer too bright, plus you managed to get a sunset photo combined with this backlit flower... I really dig the whole concept!
And I like how the setting sun paints the road in orange, giving the person some detail, and how again you combined two things: a sunset and a landscape photo.
