On the chance you’re not aware, they do make a pretty cool little matching numpad. It’s not quite as nice as having a full size keyboard (I wish they docked together with magnets or something), but for just over a hundred bucks all in, it’s a decent compromise.

*ETA: I was basing the “just over a hundred bucks” on the keyboard having been $60 on woot for the longest time, but looks like they are sold out :(
I actually prefer it the way it’s executed.
Maybe I’m thinking way too much about this, but each panel obviously takes some time amount of time to draw, and likewise each panel portrays some finite amount of time–not just an instant snapshot of the story. So as the dog is yelling at him, his drawing quality is degrading as he is working on the panel, leading to an inconsistent quality within the panel.
