Also don't forget you'll need more and more rudder and aileron as the plane slows down in the flare in a crosswind landing. Lots of landings has a slight crosswind that isn't readily apparent when you're new so you forget to apply the technique. That's probably all your instructor was saying was you weren't recognizing or correcting enough and ending up landing crabbed.

Don't sweat the hours. It really isn't important. When you first do it by yourself, you'll be even more proud because you know you worked hard for it. You're probably right on the cusp, but for a cfi to step out of the plane they need not only you to be proficient, but the right weather and you to be on point that specific day.

What plane are you flying? If you can't tell I soloed a piper tomahawk.
