Yes, this and it may be that he just photographs subjects that are more interesting than yours. Anyone can take a picture of flowers, but if you take your time to compose the shot and put some thought into what leads your eye in and around the image, symmetry, lighting, too much or too busy, group of three, tight crop, etc. There's more to taking a picture than just a snap shot.
