I try not to review battles because I don't think I'm knowledgeable enough to know what I'm even talking about. But, if my opinion counts for anything, here it is. I'll keep it short.
DC, your delivery did need a little work. The flow was there, and you still had some nice lines, made me smile/laugh a bit. Just work on that delivery, give it some UMPH, and you'd be good, I think. You definitely had lines that relate to your opponent, so that was good.
WS sounded good in this battle. Maybe because it was his own beat his had to rap over, I dunno, but he sounded good. Good flow, good lines.
My vote goes to WS.
The "Yoga Flame" sample was good, DC, I liked it... and the "You Lose" sample was good, too. All in all, I was entertained.
