I agree with above on the close-ups.
Experiment shooting with the highest f-value (aperture) possible. Zooming into the subject makes the depth of field effect stronger so you might want to try that out too.
EDIT: Oh yah, my favourites are the first one with the water droplets and the wide close-up of the dog.
