Looks like you went overboard on sharpening, making some of the noise more obvious.
One has to do something pretty fantastic and creative with water drops to make them new and interesting. What may work better is the same shot with your reflection in the drop.
The second shot is more interesting to me, but some basic technical issues are getting in the way, like focus and color.
Sharpening an image is not equal to focus. If an image is in focus, sharpening becomes something used subtlety, if it is even necessary at all.
Bee shot looks too saturated.
Hope this helps!
