In rhythmic gymnastics we have to 'point' our toes out or 'flex' them. Also, whenever you do a performance you have to stand on relevez which is standing on flex or toes. Several times, Lizzie wasn't doing most of this at all and at the end of the performance her back foot was not pointed.
In a routine, you need at least 3 balances and 3 turns, Lizzie only had one turn and 0 balances.
It's also likely Lizzie should have been deducted at least 7-10 marks for these mistakes. [Ed. A check of several sets of rules shows a variety of requirements for a routine, so it's hard to say how many of these things may be goofs.]
