Gramham technique - standing contractions, twiddles, core training, jumps

At first we started with the flat backs and i feel my first flat back was very good and my arms staied strong and straight at 23s. I also feel that my second position was good and my feet were wide. My second flat back wasnt as good as my first as my head was too far down therefore it wasnt completly straight. Another time thins happened was at 1:59 my head was again too low.
We then moved on to contractions and at 2:35 i feel my flat back looked good as the contraction come from the lower back looked breath taking.
At 2:40 twiddles start. when we first started them i need a long neck and
need too look up more. 3:16 arms start to drop so i need to keep them strong throughout the whole thing.
3:34 core training starts. I feel my balance was good but i need to have a bit more stablity as i do start to wobble at some points. Things to help would be staring at a spot, lift head and feel confident or feel you have a 3rd leg and thats holding you up. Also keeping my arms still could level out the balance and keep me stable. When i lower my back also i should keep everything sucked in.
We then moved on to pulses on the floor. I felt this was quite strong for me as i was quite low and kept pulses goind, i did fall down at one point but i should keep going, not quit and carry on working my abs. Also when doing sit ups i felt this was a stong point for me too as i carried on going and i felt i had good pointed toes when doing them. We then worked our abs by standing on toes and fore arms, i need to put my bum now to work my abs more.
we then started on out jumps, theres alot i need to work on like keeping my balance whilst doing but i felt that i did strech my leg out far but could have been further. I also need to tell more of a stroy when doing it and show more of a passion for the dance, show that it isnt just a dance that there is more to it and a story and feeling in every move i do. I also feel my arms need to be alot stronger when coming out as they should be sharp and not just thrown out.
