Compare and contrast
This might a good moment to compare and contrast the new version with the old one. Here's my original version of the page, drawn in 2013:
I remember being very pleased with it. I felt I'd gone up a level. Now, eighteen months later, I'm trying to work why I honestly thought it was good. I seem to have drawn a child's toy tugboat and tried to pass it off as an ocean-going passenger liner. Also, the buildings on the right seem to be made out of Lego and half the passengers have clothing made from plasticene. The logo and the left-hand crate aren't bad, but that's about it. Ow!
There's definitely an embarrassing side to making progress as a writer or illustrator. In the early stages, you think you're doing great work and you can't understand why you're not being picked up for publication. 'What's wrong with those publishers, why aren't they interested!?' A year-or-so later, after several hundred more hours of practice, you look at the same work again and the reason is painfully clear. D'oh!
