New In studio, Need your help

I'm new to dpreview, but my cousin told me about it.

I just started studio photography and keen to get all your feedback in order to enhance my techniques. Specially that my next shoot is about gymnastics, which is very tricky in the setting of the lighting, to show the correct curves, and to expose the correct areas of the body.

Here are some of my previous shoot, which I wanted to show strength, muscles, macho attitude and anger.

Appreciate your help.
