could do with some help iv never wrote a metal song before what do you think so far?

Keep the Dark Inside
Cage the beast in my mind
Lock away the hatred
And suffocate those who need me

Can’t get out, won’t get out
No need to live when there’s no need to fight
Unleash this beast, release my fury
Don’t cage me in
Im stronger then I’ve ever been

Throughout the age’s men stand and fight
For there freedom, for the sight
With battle hammers
And b****** swords
They sever your heads
And beg for more
