Nice work getting to where you are yo! I would recommend you learn the Kim Yeong Min trick we did for the first Trick-a-Week of the year.
It shouldn’t be much of a step up in difficulty from what you know already at all, just different maybe. The trick also has some really great yocabulary to learn that will be very helpful to know as you dive deeper into tech. And it’s just a cool picture trick that is fun to do and impresses non-yoyo people.
You can ask me any questions you have about the trick here or in the Trick-a-Week thread and I’ll be happy to help!
