As you begin your engineering education, Jen ... it helps to understand that tracking IS mixing ... for what you put to tape has immediate limitations on what can be "fixed" later ... and everything has to play nice together as you put it together.
Bear this in mind as I critique what you've done here.
The keys are tracked fine, but the sound presented is cheap midi keyboard, which actually can be fun to play around with to get something interesting.
Try taking all sort of effects, delays/flangers/doublers/choruses etc ... and twist the heck out of the sound so that what you wind up with is something very interesting and different ... a unique sonic signature, if you will. While doing so, on a simple arrangement such as this ... make the keyboard sound as big, wide and full as you can.
This technique is done all the time by top engineers in order to take something that sounds amateurish or mundane and morph it into something that has a professional sound to it ... when it's nothing more than playing with layered effects. I've done it many times myself w/
my Casio CZ101 ... a cheap
midi mini keyboard.
This song is an illustration of the technique I just outlined. The keyboard is a cheap sounding Roland ... doctored accordingly to what I said above.
That said; you tracked the vocal marvelously clean ... but ... (there's always a but, isn't there?) I think you may have whacked the mic or mic stand a few times as there's an occasional low end "BUMP" and/or rumble that occurs throughout the track.
That is the type of thing that cannot be removed from the mix later, so pay close attention to such details while tracking ... for there is no way to eliminate that type of noise from a track w/o killing the track itself.
A good way to hear that sort of thing is to solo the track itself w/o the music and just listen to it on it's own. You'll clearly hear all the other things that got recorded while you tracked w/o the distraction of the music.
It can be a bit frustrating and disconcerting to listen that way at first, but you'll improve your tracking chops if you do so ... for you learn first hand what it is you need to pay more attention to.
Now THAT said:
Great performance, good tune.
Good start!
You're light years ahead of where I started from.
Best,
