Tremolo picking 250bpm

Been grinding on the tremolo picking from the wrist. Felt like I had a breakthrough the other night and decided to capture some of it on video. I’ve been mostly doing tremolo one string at a time and then moving up and down the other strings. I decided to do that but also to add in little single note sequences that come in on the down beat to keep me honest in regards to the metronome and also just to help me keep things tight in general
