How do you maintaining and slow down on cat trails? sometime it is too narrow to do any wide turns for beginners. I tend to feather down in narrow runs.
To maintain a slow speed on the narrow trails you have to make sharp quick cuts. The sharper angle they are, the slower you will go. Carve with a little bit less of an angle, and you will go faster. Your skidded turns look fine, I'd just suggest you lean into your turns a little more and use your edge to carve the trails. You need a little more speed to do this, but once you get it down you will have a lot more control.
