hey there,
in my opinion this is a really great way to introduce new users to the way it's done.
you also said, that it is supposed to give the user an understanding and introduction to the process, not an interactive tutorial containing each and every detail.
BUT, I think that is what most new users tend to do. not everyone, of course, but in the worst they feel absolutely lost and helpless, stumble upon this thing named guidebeast, and rely on it 100%.
therefore, I think that in the UniBeast guide,
the red arrow on the fourth screen (Disk Utility) is somewhat misleading.
it is not pointing towards anything mentioned in the descriptive text in this particular step.
my suggestion would be to either remove it, or, make it point towards the usb drive in the list on the left (Select the USB Drive…) and you might as well insert a second arrow (number them?) showing the actual Partition tab (…and go to the Partition section).
this is just my opinion, as I tend to explain things the DAU way...
nonetheless this is an awesome thing you put together here
kudos!
