Mario,
The clarity & spaciousness of this piece-sonically is broad & rings out with authority...you did a great job with the effects.
Composition-wise,the shining moments of this song,are the first 9 seconds of this song,the area between 2:07 through 2:26 in reference to the drums,bass & guitar(the entire e.guitar track is great),but the rest of the song I would suggest you scrap & start over,because there's too many problems with the lack of harmony amongst the string tracks and the bass line in the area of 2:26 through 2:55 is pretty incoherent.
The guitar in the latter part of the song doesn't fit,as there's nothing to really support it.
I'm sorry for being so brutal,but these are my honest observations and opinions,which are always meant to be constructive.
I don't know exactly how you feel about this version personally,but if you're still unhappy with it,I would love to do a collaboration with you on this,as I would really enjoy building upon the areas of this song that I think are strong,& have potential.
If you're interested in doing a collab with me on this one,I would like to emulate your orchestral compositions using my orchestral sound sets,but re-work the harmonies,without changing your string work too much.That being said,if you could leave out the strings and the guitar at the end of the song,and just send me the drums & electric guitar tracks-that would be great(if that's alright with you).I think this would be a fun project to tinker around with and if nothing else,perhaps my ideas might generate some ideas within you,so that you can take your song in the direction that you will be most pleased with.
