Not bad - quite catchy but neeeds a bit of polish on the production side. Vocals need to be more prominent in the mix. Bass needs to be centrered in the mix - it's slightly off to one side and very noticeable on headphones. Like the bass parts in the chorus. Change the reverb on the drumkit - less is more! The guitar could do with some chorus effect. Try this on the guitar - make 2 copies of the guitar track. In your mixer pan one copy hard left. Pan the other copy hard right but with a short delay of about 35 to 50 ms.
In the digital domain - or any DAW (Digital audio workstation - essentially a PC dedicated to making music) it's as easy as copy and paste is in a word processor. The days of the large mixing consoles, impressive as they are, are truly gone.
