Tip Don't be afraid ...

Tip

Don't be afraid to crop/cut very aggressively.

A lot of photographers try to show as much as possible from their models while in reality it's often way more interesting to be really tight with your composition.

 

Your mind will fill in the "blanks" but cropping this tight will really give you the sense of "being really close"

 

This same tip works like a charm for sports ;)
