Well, kudos to you for working to strengthen your legs by riding in two point. I majorly suck at two point, but since I dont' jump, I don't really need it.
In any case, I agree that the way you have your foot turned out is causing too much tension (or maybe the tension cuases the leg to turn out). But in any case, you look quite tense, or "forced". I see this not only becasue the foot is Penguiny, but becasue you have your lower back rolled too far forward. YOu spine looks really tight into a "C" shape.
On the good side, your horse seems relaxed and you are riding so very careful of his mouth. Really, if you could get a few lessons I think you are doing rather well and will progress rapidly.
