pointers on my butterfly

It is hard to get a good look at your stroke from that video. I can't see your hip position nor get a really good idea what your kick and timing are. I think your shoulders are low in the water and you have a somewhat unusual windmill style of swimming fly. Just a guess but your shoulders might be low in the water because of a weak kick. You are fortunate to have good shoulder flexibility - otherwise your arms would skim across the water. If you watch Phelps swim his kick is so strong that his upper body/shoulders just surges at a perfect height above the water. His arms rotate forward parallel to the water instead of yours - which point high at an angle toward the sky. If you get a chance to shoot more video - shoot from an angle or the side. A little height would be good too. I couldn't have said it better myself! Very very hard to see what is going on underwater here. I agree with the arm position, etc!
