The guitar(s) seem slightly out of tune - mostly noticeable toward the beginning - perhaps I got used to it more as it progressed. Mix was fine - good balance between the guitars.
From a purely songwriting perspective this was a tough piece for me to follow. It's an eclectic mixture of guitar parts that intertwine between each other. I notice that the title says "Improvised". It stays on key all the time so that's not a problem. The playing is also good. But as a pop radio listener I would have liked to get some consistent repeating parts (hooks as you would say) that I can connect to. It's just too random for me to grasp onto - again I like pop music so take that into consideration.
