well i will say 4 tips for you
1) Try to go slower with your openers speed so you can work both in the same speed
2) dont keep your knees to bendet (idk how to spell that) cuse it looks bad

3) Dont keep yours arms too high or u will have trouble and your tori will lose balance

4) Dont do glitchy stuffs.
u sometimes extract then contract again that doesnt look good
just keep them relaxed in most bids.
