Thanks guys 
That’s some good feedback Johnathan, thanks for that.
I’ll admit I didn’t do too much panning on this track so there’s room for improvement there. I agree with you on the ‘empty’ sound, especially after listening the 2nd half of the track, the first half does sound a bit bland (the acoustic guitar + strings in the 2nd half do a decent job of filling the piece up in my opinion.)
There’s some small mixing things I noticed in certain passages as well when listening to the track today, so I’ll get back to fixing those.
There is a reverb track actually, but I tried to keep it on the low side because it would quickly drown the song when I increased the reverb times. I could automate it a bit to make the ‘cooler’ passages a bit smoother.
As for layering, both the bass and the lead are actually layered sounds. I’ll try to seperate the layers a bit with some panning, I didn’t think of that.
Cheers for the feedback, I’ll hopefully get a chance to go back to it soon
