Hi Patricia,
I hope you don't mind - I've done some color and distortion corrections on one of your photos. I've found that the spherize filter set to -3 or so will eliminate that fish-eye look that the lens casts on photos. A bit of keystoning helps too.
This is the one I would paint - I warmed up the background and her flesh a tad.
If I was going to reshoot - I would go for a touch of a smile - something enigmatic - think Mona Lisa.
I'm a bit less-than-qualified to offer these opinions, but - here they are anyway.
Good luck.
