Best Work and Improvement

This image suffered from some lighting issues - this one, is over exposed - too much light - the image was taken under two bright lights and the exposure setting was increased.

This photo uses more natural lighting and isn't over exposed. 

This photo had issues with the lighting. The environmental portrait is using desk lamp (tungsten) lighting and there is also a window or big natural light source behind them. 

I constructed the setting so that the natural light was falling onto them and not just back lighting them.
