It's a bit sparse. For the most part, you only have one or two tracks going at once, so there's not all that much to listen to. 1:30 to 2:00 is the exception, and this is where the song gets a bit interesting. Unfortunately, that's two thirds of the way through the song. That's way too long.

Your problem, and this trumps any others you may have at the moment, is that your song is poorly structured in two ways. It has badly defined sections, and its sound is sparse and missing some essential parts.

Generally, most songs are structured this way:

Intro
Verse
Chorus
Bridge
Verse
Chorus
Outro

Some songs have more parts or less, others may have them in a different order, but this is a good starting point. Each part should have a musical idea that makes it distinct. Your song feels almost entirely intro until about 1:15 or so. You then get a verse/chorus at about 1:30, the song starts to get interesting, but then it ends at 2:02. Thirty second outro. With 2:00 of intro/outro, and :30 of actual meat, your song is very imbalanced. Each of the parts above should be roughly the same length. If each is, say, thirty seconds (which at ~120 bpm is around 16 bars), you have a 3:30 long song. Perfect radio length.

Now, when you're writing a part, you need to make sure the sound is properly filled out. Most of your song is only one or two instruments at once, which is pretty boring. Keep in mind that a full sound has five different parts. Parts in parts!

Note this next part is paraphrased from The Mixing Engineer's Handbook:

Foundation - The rhythm section. Usually the bass and drums, but can also include rhythm guitar or keys if they're playing about the same musical figure. As the name implies, the rest of the sound is built off of these instruments. If the rhythm section is done poorly, the rest of the sound is going to suffer along with it. Even for songs without a strong bass beat, they still need something that emphasizes where the downbeat of a bar is.

Pad - A pad is a long sustaining note or chord. This can be provided by synths, guitar power chords, orchestral string sections, etc. The pad provides weight and meat to the sound, gives the listener something to bite into, if you will.

Rhythm - Rhythm is any instrument that plays counter to the foundation. For instance, if the foundation is emphasizing beats 1 and 3, the rhythm guitar might emphasize beats 2 and 4. This provides motion and excitement to the track.

Lead - The lead vocal, lead instrument, or solo.

Fills - Fills generally occur in the spaces between lead lines, and can help transition between one section of the song and the next.

As with the song parts above, not all songs follow this pattern religiously, but it makes a solid starting point.

Rock band instruments are MIDI compatible. My irl band actually recorded a demo with a rockband drum kit.
