Your Seagull picture is well composed, and seems corrected exposed on my laptop. The B&W picture of the Palm tree is a nice composition. I particularly like the sun rays effect through the palm leaves. I keep on looking at it, and it seems that if you cropped it so that the bottom of the picture is just below the smallish leaf, it just becomes that much stronger of a composition. Below that line, it just dead space that doesn't seem to add anything to the picture.
