Help me decide!

So all my shooting lately has me realizing I am a little clueless on great lighting for portraits.  Sometimes I get lucky and it works, but to grow I need to know what to look for.  I have been reading a lot and read this one last night...just what I needed.  I am looking for that light that makes skin tones beautiful and eyes sparkle.  Levi and I went on a walk for me to practice today...he was not a very willing subject!  I need an adult to let me direct them around all day to really practice.  Anyways, I just edited one sparkly eyes photos...I am also practicing editing...so help a girl out.  Do you prefer edit one or two, or be honest and say "I cannot tell the difference"?  Please leave a comment to help me out!!!  Thanks.
