In terms of composition, this is a great track. Keep it, don't throw it in the trash.
In terms of instrumentation and sound quality though, There might be a bit of work to do, the guitar sounds really too flat and dead.
Also, I don't know if that's gonna help you or not, I just hope it doesn't discourage you from the sheer number of things, but here's a quick list of things that really change how your riff sounds when you're playing guitar.
-Picking technique. (Upstroke, Downstroke, alternate picking, sweep picking, economy picking, pickslanting, pick angle... they all sound different)
-Vibrato. (probably THE sound that makes a guitarist recognizable. It's when you play a note, bend it out of pitch, back again, repeatedly. TONS of nuances in there) Legato (Playing a series of notes without picking them, just hammer-ons and pull-offs. Could almost be counted in picking technique as far as sound is concerned)
-Muted notes (Usually in a sequencer you can simulate that by having your note super short, but it's still not quite the same sound. Adds a percussive quality to your playing).
-Harmonics (now there are pretty much different pitches by themselves, but you can get a bit of harmonic to ring at the same time as a regular note)
Just combining those in a 10-note lick creates hundreds of different sounds, but it's also what really adds "humanity" to your sound. I'm sorry if this looked like a big wall of stuff you already knew, but just in case you didn't already know these, it's worth checking out each technique separately. There's literally so much a guitar can do, if you just take the extra time to modify the sound and add some irregularities, it'll sound 10x better.
