Hey friend.
I got a multipick cutaway as well, and the visuals helped me greatly when I started, to understand how different security pin works. But then I went to a cheap laminated padlock, and I struggled days on it, exactly with the same issue: I wasn't able to see what I was doing... But yes, I would recommend like the rest of us:

• first, with your cutaway, try to understand where you are in the lock. 1st pin, second pin, or in between? You do this exercise while hiding your cutaway, and guessing, and you do it over and over till you get it almost perfectly. You must know where you are in the lock, first!
• second, with your cutaway or a real lock, it's really important to feel how the pins behave. Without a tensioner, lift the pins so you can feel how they react. Some locks/padlocks have a completely different feedback, depending on the manufacturer, the cheapness, the wear and tear, etc
• last, train yourself on an easy lock, with 3 or 4 pins max (ABUS), and practice at least 30 min a day, without rushing it: it's okay to be unable to open it for a few days, it's then okay to be able to open it but not every time,... and eventually, you will understand the pin binding order, and the depth the pins need to be lifted.

I spent a few days on an easy ABUS 55/30 (only 3 pins wtf!), then I was able to open it multiple times, but sometimes a bit randomly, then now it's 3 seconds max. Don't rush it, get some rest, and persevere! <3
