Studio in the nature

Most of the nature photographers prefer the ambient light. I like to control the light myself in my macro and plant photos. I tried the concept last year but this year I want to further develop the concept of using a mini studio set-up in the nature. I'm planning to use various background and light sources (via fiber optic adapters). Last weekend I tried the rim lighting in the nature. In this way I can separate the subject from the background. Moreover the rim light bring out the details and textures perfectly.
Some examples:
