it's basically like this...

punches, flow, and structure are crucial to having a good verse...and they both effect one another

if u have to write one long ass line jus to create a punch...it's no longer hard hitting and is fuckin wack because it doesn't flow and tha structure is horrible...shorten ur lines but make sure u can get tha wordplay and punch through...but don't make it so short to where it's like 4 words and turns out to be a horrible punch

that's all i can think of right now
