can somebody give me tips to improve my td raiz?

You did the move , but its was to slow and stiff and when you landed it was side ways to you did not have enough force or speed to do a successful cork or and move really also the
Td raiz imo was to low and the opener did not have a good flow or power.

the most decent cork i can ever make

too stiff, use more joints, try a more relaxed style
