On the flat, while it does look a little forced, your position looks great. I'm aiming for the same thing right now and doubt my pics look as good. The jumping pics show improvement too, but I can't quite figure out what doesn't look quite right. Your leg has no angle to it, no bend in the knee. Since your legs are very similar to mine, I'm thinking your stirrups just need to come up a hole or two for jumping. You look like your doing your best to wait for your horse to jump. Overall great improvement I'd say! Hopefully more experienced riders will ring in.
You just have to see your distance...you don't have to like it.
