You Both had nice lines here,

BASH:
Your Vocab and the way you played it was sick, especially in these lines:
Demonic Soulz-Crack Plutonic Skullz With Persistant Holdz
That Never Give up Like Sadistic Strip-Showz
Historic Music Composed , Scientifical Calesthinics Unfold
Mystical Mind , States Are Remotely Exposed - hott.

Your overall content was good, however you can use too much vocab sometimes, just try to hold back on it a bit

WEST:
I felt that your lines were too long, they could have been cut into 2 and it would've made your verse seem longer. However some of it was dope i.e.:
call me tha element mercury coz i flow like it in liquid form,at room temperature i morph into fragile so i have to handled with care and cooled down to reform/ - Tight wordplay here, and in the 'Terminator' line as well..nice

Overall:
8/10, good introduction to the 'Invincable Elements', hope to see more as time goes by!
