Thanks.
Peter,
Yes, this is supposed to be the underpainting, but as you can see it is too much of a midtone everywhere except for the lighter areas. The day I painted was overcast and sunny at times so I had a rough time with the tones.
Elizabeth,
Yes, I am painting this looking at the mirror and it is harder than I thought. I don't have bifocals (not yet

) but it is hard to have the exact pose everytime. It's a pain in the neck (no pun intended really). I have not noticed distortions but maybe I will ask my girlfriend if there are any. My glasses are not super strong.
I have come to a solution to take a picture of myself to save my neck. But I will still have a mirror in front when I paint for tonal reference.
