OK... Here's my critic:
"Summer Zone"
- The bass lacks higher frequencies. Your bass really seems located between 30hz and 100hz. You should try boosting the frequencies around 120hz and 400hz.
- The melody is too high for the drums. Lower the level of the melody. Also there's kind of a metallic reverb to the melody which can become annoying a bit. Also have you tried playing the melody in another key? Maybe one or two octaves higher?
- Do you use compression on your instrumentals? Personnaly, I compress the drums, mix them with the bass, the melody, the percs & etc and I compress the whole thing again. This could add some tightness to the whole song.
That's what I can think of for now.
"Rap Instagator"
- I really like the concept of the beat. The reverb on the snare add 'coherence' to the whole thing.
- The bass could be brought up higher and try playing with the same frequencies I told you for "Summer Zone".
- Kick is tight but could be a even tighter by shortening it a bit by about 4 to 8 ms. I hear kind of a reverb on the kick. Be careful with reverb on kicks; if not handled correctly, the kicks could be become all muddy. Maybe shortening the reverb on the kick a bit.
- As for the sample that plays most of the time... Try to make the enveloppe of the sample look like this:
|\
| \
And then adding a hall reverb to it. I don't know; I just hear the whole thing in my head and it would sound really phat
Peace,
