Looking better Stef.
A skips, maybe a bit more arm action.
Running As, good body position which is often difficult to achieve. IMHO possibly a bit too much forward movement. Focus on toe up, and really having minimal ground contact time. You should find that help.
Scissors skips the way I do them is with minimal ankle action. See how high you get and about 1/2 way through seem to be pushing off? Try and keep the ankles almost locked.
B’s don’t get the leg coming out till on the way down.
