I'd say you're leaning uphill too much. Some more knee angulation might help bring your upper body over your skis more. Try to get your hips and shoulders closer to directly above your skis instead of so far up the hill from your skis.
Your weight is on your uphill ski too often (partially because your leaning uphill too much). Switch your weight to the uphill ski only at the exact moment that you pole plant so your unweighting can be driven from that ski.
where my hips are in relation to my feet may be a visual trick making it seem like I'm more back than you think.
I think you may have misunderstood me. I am not saying that your hips are too far in the direction of the tails of your skis. I am not saying that you are simply in the backseat. I am saying that when your skis are going accross the hill, your hips are too much up the hill to the side of your skis. I am confident that what I am seeing is not an illusion. If it is it's a really awesome one. LOL
I can see it in every turn. This picture shows it:
Again, I am not saying that your butt is too far in the direction of your tails, but that your hips are too far to the uphill side of your skis. Part of the problem is that you're really straight-legged instead of angulated. Being straight-legged like that means that if your skis are on edge, your hip will be too far uphill.
That picture also shows you with too much weight on your uphill ski. The spray of snow over your downhill foot proves it.
