The page that took too long... I'm kind of happy with the first panel as it adds much needed backgrounds and scenery to the pages overall but this page is still weak in concept and over worked. I wanted to have a cool visual concept for each page but this is just 3 standard panoramic panels.
At some point during the roughs stage I tried to make the bottom two panels act like cut away designs of the tube trains interior in a similar vein to the cutaway designs you used to get in Thunderbirds annuals. I could never quite execute that properly so you're left with a weird half way compromise.
The proportions of the figures in relation to the scale of the tube train carriage's is...yeah. By that point in the pencilling stage the whole thing had become a case of trying to pull off visually interesting poses and make it still seem fluid in terms of motion. I salvaged some of that in the inking stage but it's ultimately a mixed bag.
