Hey man! Very good job in case of timming
Let's point out some issues
1. Your pinky finger get's flat while playing B power chord for example. It's not good. Look at Gab's lesson - he does a regular fingering for this chords. Looks like You replace 3rd finger and make a baree with Your pinky at some chords
2. At the part around 0:25 those muted breaks are not clean enough - we can here some noises coming out while You hit those muted strings. Try to experiment with You left hand pressure. Maybe You hold it too tight.
One common advice for all Your playing - try to change positions in the last possible moment. You break the shape at the end, before You go to another. The whole trick is to play it till very end and make an ultra quick skip to another chord. This is partly a reason of Your noise issue. For example 0:29 You moved Your hand while there should be 2 more of eight notes muted and than fast skip. You just passed the chord too early
