Deep, Dark, but seriously repetitive.
The solo changed the pace of the beat and that was a much needed relief on the ears.
Let's put it this way...this piece WOULD fit into the ambient section, but the electric guitar makes it an ineligible piece for the section. General Rock would be a good fit seeing as the mood actually fits a beat from groups similar to Shine Down and Stone Sour (they consider themselves alternative rock...) and the likes.
Maybe shave off a section or two of the same repeating lines and bring your solo closer to say 1:40ish. Reducing the length of the track might be a displeasure to some listeners, but as you sit here and listen, you begin to lose interest hearing the same melody over and over.
Just something to consider my friend :-D
