Really nice takes of (in part backlit) flowers ...
... of the red-yellow tulips I prefer #1 over #3, as #3 is so divided into two halves and although the camera focus suggests where your focus was, compositon leaves us in two minds about it.
The bluebonnets are nicely "high-key".
And the backlit white(ish) tulips against the all dark background look good, to my mind, but I'm a sucker for backlit plants... And those have nice frilly edges.
Great shots. I really miss living in Texas every springtime. I loved just pulling over to the side of the road and getting lovely shots like these. Great job, and thanks for a few shots that remind me of the place I grew up in.
