Hey, no biggie, these aŕe made from some of the most versatile transforms and difficult to get right. Their versatility is why they are complex.
I find that the more I fail, the more I end up learning, especially when I totally screw up!
Try increasing and decreasing weights of transforms at the right side of the editor to see the effect of the change on the scene.
Maybe change a few blurs in the transforms list for crackle to see a change.
