Apart from Kwing's mic, I have only one other qualm. His flow could use more work. His first verse wasn't as off-point as his second and overall he wasn't horrible, just complicated to listen to.
When it comes to deciding a winner, I'll tip my hat towards Phr0zen. His 'attacks' hit harder than Kwing's and I especially liked the 'plane hittin' cardboard' line as well as the lines Glitch mentioned.
Shout-out to Rampant for the beat. Where is the Acoustic Guitar sourced from?
