I can very well be wrong.
I have also learned Ng Lun Choy and seen other variations (as well a few CLF forms) but rarely (at least none that I recall) have outside crescent kick or jumping snap kick.
His pose is Lohan Tiger Stike pose since GM Li Iu Ling (and his students) have posed of a few photos with that pose in caption on their website. They very much look the same and like I have said it's not commonly found in CLF in that pose.
If you have a video online that highlight those moves in Ng Lun Choy I would love to see. Perhaps it was added in different lineages.
The other moves GM Li Iu Ling demonstrated can very much be CLF I don't doubt that.
Thanks for responding.
