1st Tab. BPM advice

The last bar of my first tab seems to lose Sync. Is this because the BPM is wrong or just that the Musos are out of time? http://www.hooktheory.com/hookpad/view/SmWSCQURyUNl

I think you ended your tab sync a beat too early. The ] bracket has to be on the first beat of the next measure, not the 4th beat of the previous measure, if that makes sense.
