please comment on my technique

Hi I started playing seriously last year. Took 3 months of drum lessons. Please comment and criticize my playing. This is me playing doubles at 77bpm. I am kind of stuck around this tempo for a long time. How can I improve to sound better and increase speed? Should I continue taking lessons? Reason why I discontinue drum lesson is because I want to focus on listening and playing along with music for now.
