Welcome to Clubsnap, hope you enjoy your stay here and "grow" your photography.
The first picture has a leaf in the foreground blocking the view of the leaf with the water droplets and the water droplets look overexposed.
Second picture has too much of the white background which is quite glaring for a viewer's eyes.
Third picture is just about the plant that is seen everyday with the shallow depth of field.
If possible, try to add captions or titles to your photos, if possible a short write-up on what are you trying to tell the viewer.
