It's not too bad. There's parts of it that don't seem to mesh up with the vocal part, melodically. It also sounds a little flat, like things could use some EQing (specifically the drums), might just be how I'm hearing it, though. I haven't listened to the original enough to give a better "critique" of it as a remix, but it sounds pretty good. The intro has a nice hook, and the ending is smooth. And welcome to MLR! If you ever have any questions or want help with the DAW you're using or just questions in general, be sure to check out the Technique subforum, there's a lot of helpful resources there. Keep it up!
