yet again agree with sprog. really really get the basics rite. I regularly meet peeps who flail around like pengiuns on acid who say 'cant weight to get in the gym and start flip training'. They would not be flip training, they would just be throwing themselves at a crash mat!
Just keep your chin up look str8 ahead and try to bounce higher and higher ( do it in front of a brick wall, you can then check how high you get AND at what point you are highest-at which point tricks are performed).
Your split kick seems good so dont worry. A vid that shows both the ground and your head in same shot would b good so posture , and height can be noted and advised apon
