While I was happy with the 'Alex Toth' lettering font, and balloon style, the letters seemed a bit too close together (possibly to do with the default settings on Manga Studio 5) and the tutor had suggested some further work on getting the spacing right.
I increased the line spacing from 0 to 1.5 (although it's upper case, the hand-written aesthetic means that some letters are slightly raised or lower, and in particular the 'M's have long tails that were a bit too close to the row below. I increased the character spacing from 0 to 1. I quickly resized the balloons to accommodate the more widely space text, but this means some of the balloon tails need adjusted.
This same page, with the lettering in it's previous state, can be seen, for comparison, below on the 'Page 7' post from 19/7/2017.
I also applied the same lettering settings to a page which has a different style of balloons. Looking at this now, the above style looks better. I think it's perhaps to do with the more rigid edges on the balloons below clashing with the looser lettering style, and in particular it's variation of vertical position.
Below I changed the balloons to the type I preferred on page 6, as posted previously. This generally works better, though I think I can still finesse th pacing and edges of some of the balloons.
There were still a couple of methodological issues though. In panel five the double balloon is Uccello speaking, which hopefully the rider can be clear about because his wife's balloon has a tail pointing toward her - it was hard to find a place where a tail could end, because going to the edge of the panel to the right, meant it was going towards the figure o his wife in panel 6. I tried running it along the lower part of panel 6, up to Uccello, but that didn't look right either. Also, the text 'into this?' continues Uccello's unspoken thought from the previous page, and this doesn't work as well as version one (top) where it is clearly a thought bubble, distinct from the word balloons. I'll need some more wrought/work on that.
The borderless balloons and tails do tend to look better where they are on a flat colour, as in panels 3, 4 and 6, above, and less well when they are over drawn details.
