Hi Tim. You've got a good right hand strumming technique there but the timing is a bit off the rails
The other guys have obviously said this already but I would add that you can also divide the lesson up into smaller chunks and focus on playing along with the original lesson so you can hear if your guitar is in synch with Diego or not. Just focus on getting the first few bars right and keep repeating it until you feel you've got the groove. Then move onto the next few bars and repeat.
