hey! i think theres an easy soulution to your jump problem and thats simply practice. If you take atleast 10 mins everyday and sit in a split and stretch it will help, and after you stretch you should try to do at least 25 jumps of each. Even if they are bad then keep going it will help. But make sure while your jumping point your toes and keep your legs straight. Its a lot easier to get perfect form when your first trying out then it is after you already have a jump. Also if you have access to a trampoline you should try practicing jumps on that becuase you can get the height that you need and it will help you get a feel of what your jumps should look like.
as for the facials i would say do anything that comes natural to you. Practice in the mirror lime cute little faces. Also what i found that judges like is if you say some of the words that are in the music, but put attitude to it. And believe it or not judges like it when u wink at them! just what ever you do DONT STICK OUT YOUR TOUNGE its not pretty believe me!
well i hope this helped you!!
