We viewed your photos and notice old flower heads from the spring and spider webs. Spiders are predators and help keep pest insects in check. They are not harming the plants. Looks like you sheared the plants.
The best method for pruning English boxwoods is thinning. This allows the center of the plant to receive adequate sunlight and good air circulation. The best time to thin boxwoods is December through February. The temperature should be above freezing.
