I like it. I always have a hard time photographing YELLOW flowers but yours look awesome. It is well composed and I like how you have post-processed your image. This looks like a painting I would hang on a wall.
Holger, This is a great shot. The 2nd bird caught in flight makes this a much more appealing shot than just a single gull. Bird in foreground is in sharp focus and b/g is slightly blurred but you get a good sense of where you are. Congratulations on an excellent shot.
