When the weather gets colder and the days get shorter and grayer it is fun to shoot some extreme closeups of natural subjects in the studio. When I am photographing outside I collect subjects to photograph in the studio at a later date. My favorite is feathers, but leaves, seeds or almost anything natural can be interesting. Your studio can be your kitchen, living room, etc. or an actual photo studio. It is fun to try stretching your photographic vision in a controlled environment to see what you come up with. It can be extreme closeups of everyday items in your home or natural items you find and bring inside. It is interesting to see even a slight change in angle or shift in lighting can make a big difference in your final image. Simplistically, shooting parallel to your image gives you more depth of field across the subject, shooting at an angle gives you more of a view to highlight a certain area in sharp focus and a softer look in other areas highlighting a certain area you want to show. Also you can use many homemade items to add to your image. Try a small reflector or mirror to bounce back a little highlight to an area or even a white fill card. Lighting from above and behind adds more to surface textures. It is fun to try different techniques or just experiment to see what you get. Another technique to try is focus stacking, especially for closeup macro shots for more depth of field in your image. Images below are from 1X to 6 or 7X with a variety of macro lenses. 50mm macro, Canon MPE 65mm , 100mm macro and 150mm macro.
