OK. Maybe you just need to slow down a little more, and I find that filming a single and just watching it helps too. You can just move your wrists and look at the other side of the cube if you cannot find a pair.
You need to be able to be familiar with how to do each case - at your times, you should be capable of that. I'm not that far away from you - I am 23 secs. What helps me is slowing down during Cross and F2L (Slow during PLL and OLL is pointless) and going as fast as I can during LL. Then I can get 20 sec or even sub 20.
Try this, and it will be kinda difficult, but stick with it for 3 days, and if you have any problems, feel free to PM me. As you know by now, this takes practice and paitience. Good Luck!
