help understanding boot issue

I'm making slow progress and making a few mistakes along the way but I think (or hope) Im learning.

I'm getting stuck booting up OpenCore with the USB, does this Log mean anything to anyone? or can I provide anything else to help work out where I'm going wrong?

​

Thanks
