Without getting into the psychology of being
a 'hermit freelancer' there are times when
you try to work because it's a workday but
something is usually lacking.  

Initially, I changed the first page because the
action in the first panel wasn't clear and the
angle was very similar to the first panel on
the next page.
Then I decided the figure in the first panel of
the second page wasn't dynamic enough so
I changed that.
In both instances I completely redrew/traced
the page because the paper wouldn't have
survived a redraw.
There wasn't anything wrong with this page from a purely
illustrative point of view but it felt too fast paced for the
story-- so I redrew the page with a static opening that
suggested GROK had been in the chamber, pleading and
arguing, for some time.
This was one of those times where the
image looked terrific as a frenetic thumbnail
but lost everything when I removed all of
the construction lines. Without them, there
is no sense of scale and the Tripods look
thin and feeble.
