I thought you did a good job with this. It's always hard when you have a track is as referential as this because the listener can't help but compare the two. I won't do that and just say that if your goal was to create a "Get Lucky"-derived song, I thought it was well done even if the mix does need a little work. It definitely had a groove, and if you can find someone who can lay those guitar and bass parts down for you then it would definitely be bangin.
