Thought I'd throw in my two cents for ya Phil.
Overall you look like a strong skier and it appears as though you drive the skis through the snow nicely.
In picture 2 (below), I just added some ideas.
The line I drew at your waist is just about where your upper body begins to initiate the turn before the rest of your body because your upper body is opened up, but your skies are still flat and appear to be coming across the hill. Your pole basket (the circles) in the circle on the right signaled to me that you're moving more laterally and lacking some forward motion, which could lead to this initiaion with the upper body. If you swing your pole more towards the tip of the ski (the open circle on the left) instead of downhill, I think you could close your upper body and flow more "with" the skis.
In picture 3 (below):
There were just two things here. One is the hand position. I drew a line across your current hand position and then drew in the green line to represent a more appropriate position. What can happen is that by tipping, you can loose a bit of pressure control on the outside ski, and I think that the very very slight A-frame you developed stems from this - to prevent the loss of control, you tipped your outside ski just slightly more than your inside ski. (that's just my guess though from the picture).
The two black lines along your lower legs show that slight A-frame and the green line shows where your leg would be if you opened it up a little bit. Along with opening the leg up, you could extend it more and get that 'long and strong' outside leg to allow you to flex and extend appropriately throughout the turn, and because of this I think it would lead to better application of pressuring movements. It kind of goes back to the angluation vs. inclination (or tipping vs. setting up angles in the body). You're not completely tipped in the picture, which is great...but you could level out the hands a bit and set up a bit more of an angle between the lower and upper body and I think that would help things out as well.
I just wanted to try to show a little bit better what I was talking about, so I drew in all the lines. Hope this helps a bit. Like I said before though, you look like a solid skier, so keep up the good work!
