Very nice tune! Love the sound of the guitars and the synthy strings fit in well with it. I like the added melodies a minute into this too, kept it interesting. I liked the transition made at 1:40, there was good use of EQ effects in this part. About the mix, I think the overall sound is pretty well balanced, I could make out each instrument alright. If your're looking for something to improve on, I feel that when the electronic melodies were on high notes the frequencies were sounding a bit sharp. So maybe reduce the Hi frequency on that part a little?
Keep up the good work, look forward to your next submission!
