The point I want to make here is that the way to hone your skill and develop a style, is to shoot often. If you are interested in flower and garden photography, architectural photography, nature photography, fashion, trains, or any other genre -- you need to shoot often to better your skill and competence, as well as find a style that gets your creative side going. Not everyone can shoot some subjects every day, but flowers and gardens are good training and preparation for other types of nature and landscape photography. Shoot at different times of the day -- even twilight, to see how lighting changes the atmosphere of an image. Wet flowers and grounds after a rain give the garden a totally luscious look that is absent when everything is dry and less intense-looking. Try different focal length lenses and see how they affect your scene. This is a good time to become familiar with your tripod as well. I recently set up my old plain-prism Nikon F with the standard 50mm f:2 lens, a roll of Walgreens 200 (made by Fuji) color film, my sturdiest tripod, and a cable release. I wanted to shoot in the garden late in the day at f/16 and see what results I might get.
I'm thankful to have such a lovely photographic playground!
