You should come up with Alt Text for hovering over the images.
I always find those great with webcomics.
Sort of makes me upset that I don't get to see witty/secondary jokes when I have a material comic.
An Alt Text for the first comic could be something like "But I wanted to be doge..."
You should also try things that can't physically happen in Blockland.
For example, Blockhead gets out a music brick and tests it out.
He looks and ponders for a moment.
The next panel shows him walking down the street happily with 2 music-bricks strapped to his head as an improvised set of headphones, much to doge's dismay.
