i need some opinions about my rap,i just did it in 5 minutes?

[mr.fantastic]

my word flow through the pen
and bleed out on the paper
i met the reaper
and said man see you later

one i get started
i can't be stopped
when i come through the room
competition sweats
cause they know that im hot

whose cooler than me
nobody else
can't nobody do something like this
nobody else
