Megan, welcome to the forums.
Picture #1 while not exposed suffers from a blown out background that distracts ones eye from the subject. Try to tone down the background some.
Picture #2 the bird is way too small to be the prime subject. You need a major crop here.
Picture #3 is nicely composed, well exposed, and the colors are controlled and nicely saturated. The best of your set.
Picture #4 is also very nicely composed, but the bright contrasty light is creating major shadows under every leaf.
Picture #5 (the fence) is some what over exposed. also that out of focus flower right in front of the fence is very distracting.
Picture #6 is nicely composed and works well in B&W. You could re-edit to bring out some blacks as there doesn't seem to be any.
Picture #7 just doesn't do anything for me. Not that well composed, as the flowers are just there.
Try to post less pictures per post if you want CCs. Also your Watermark is kind of bold and just not needed. If you really want one, then make is less visible, and smaller.
