Guitar sound is very good I believe. If you want some critique on the sound, here it is:
1) There are parts of the song where the guitar gets a little lost over the drums.
2)The beginning part sounds like you have a little too much going on in terms of the various octave, steps up and down, I don't know what you were going after but to my ear just a little much going on with the pitch pedals (synths).
3) Right around 2:15 to 2;30 the guitar sounds a little muddy.
4) Last, around the 3:00 mark the sound is a bit too orchestrated for my taste, sounds like whatever effects you are using, they are overtaking the sound and making sound too much like an orchestra.
Other than that, I think you have a good start there my friend, its obvious you have worked hard on getting the whole thing together. Excellent work!!!
