Advice goes best with sharing examples posted here. They don't have to be from this nice level posted above to get started. But you have to start practizing to get there...Jesse, A great set of images! Yes lovely eyes and smile. Nice light! Love #3 as well.
Now I can appreciate how difficult it is to take nice portrait like this. I shot one on Saturday and the shadow around the chin appealed horrible.
Can anyone advise where I can pose such pics to get suggestions for improvement?
