Practicing at Home

FEEDBACK APPRECIATED 

These are shots I made to practice the various lighting techniques.  I do have a tendency to lean toward creating black and white images - but I'm working on it.  Please feel free to give your feedback - tell me what I can do to make better images!!!   Thank you...

I brought a $30 neewer softbox and cowboy flash off amazon- the background we already had for video interviews.  The difficult part for me right now is taking what's in my head and using the light to make it happen - but I assume practice and more practice....
