Hello.
The Good:
-You really got the funky bass down, same for the saxophones, which sound incredibly sexy.
-There's some nice variation in both sections, and it's fairly impressive that you remixed two songs in the time it took.
The Not-So-Good:
-There's a lot of dissonance in some places, such as in the first flute/harp solo.
-The drums are fairly dull and flat, aside from the cymbals.
-At about 2:35, it gets fairly muddy and hard to hear most things.
-The transition at 3:30 is extraordinarily rough for no good reason.
-The piano and most of the brass instruments are fairly weak.
-A few mixing problems from about 4:00 to 4:20 on the right.
-This shouldn't be one song. It's two different pieces remixed in different ways without even a transition between each other.
Overall: Score of 5/10. Main problems are the flat sounds of the instruments and the horrifying transition. Sorry for not having much to say in the "Good" section. There wasn't much I could think of - I'm not saying there aren't good aspects, but there were none I could verbalize easily. Also, I really wish you hadn't essentially made two tracks and then crossfaded between them. It seems dangerously close to cheating.
