I found these on Alan Davis' website, character redesign sketches of the Knights of Pendragon he did for the second series, from issue #6. I've cut and pasted each image from the original scans to highlight the detail, some are very blurry, but you get the idea of what Alan was trying to achieve.
He had this to say... 'I remembered pencilling this cover but had
completely forgotten that I redesigned these
characters until I came across the copies below.'
I loved the redesigns, apart from Union Jack, Alan Davis gave them a more contemporary feel!
