Although I have drawn the last page, I have some panels to go back and add, including one of page 15, as shown below.
It's slightly technically complicated, as I've got to get from Uccello sitting in panel 4, while he stands holding up a drawing,to panel 6, where Uccello holds up a drawing as the patron, Salimbini, sits on his stool. Also, Rocco (the patron's 'major domo', in brown jacket) is there, so what is he doing? It's so long ago I drew this, I have been unsure what my initial plan was. I had been assuming the figure to the right of my sketch for panel 5 was the seated Uccello, but I I realise now that (from my roughly sketched hat!), it is Rocco holding up the drawing, with Salimbini on the right, panel 6 then is almost a mirror image, with Salimbini turning to look at Uccello, who is holding up a drawing to juxtapose with the first one: two drawings of horsemen together now suggesting they joust each other. I think it will be confusing to have Salimbini drawn as if he is sitting, as we don't seem him in the act of sitting, or him on the stool - it's just the head height - which might just look like bad drawing!. Panel 6 was an early one, and may be worth redrawing anyway. I'm thinking now I need need to overall the drawings - it's probably better to let the reader have to imagine it - just as the patron is. We see the two riders coming together in joust, anyway, in an imaginary/symbolic scene on the very next page. So I'm concluding that the arrangement works, if I just make Salimbini standing. I had thought about turning it into a single panel, perhaps with a double image of Salimbini facing in each direction, but I think two panels will be better, as I captures that a moment has passed between Rocco holding up one drawing, and Uccello holding up the other.
I also have to add the drawing of the hat on the wall in a number of panels.
I also have to fix the lettering, from the widely spaced version seen on most of this page to the better spacing, and smaller size seen in panel 4, above.
UPDATE - I've just realised why I had the patron sitting down - him being lower down means he's not in the way of the drawings for the reader. Still trying to solve this...
I've redrawn the figures for panels 5 and 6, ti work as a pair. I've still finesse the composition the horsemen drawings and the paper edges.
I've now added the drawn images and the pieces of paper they are on - it was a bit of work getting these three elements and the word balloons, all composed together nicely. I placed the drawn images so that those parts Uccello didn't draw (i.e. they were hidden behind other riders) are hidden in the rolled parts of the paper.
