In addition, I know it is only a small touch but the extra panel border, with the last panel on the first page, does make a big improvement.
I think he did that to hide the line across the original panel, which is from the fact that the bottom part of the panel, the eyes, is a stat from another page. I have the original b&w page of this. Clint's used stats on a few Misrule pages, and on some it is hard to make out where the stats starts and end, as they have also been radically altered in some cases.
Whilst I prefer the colour palette of the new colouring, I think it's a shame it hides so much of the linework that I admire in the art.
