I swear, you're getting better and better.
The one problem I have with the text boxes is the outlining. Thinning the lines makes them look better on a sprite comic, and that also gives you more room for text.
The humor has improved drastically once the third comic came about, and you're slowly getting better at presentation, as evidenced by the most recent comic.
However, with that said, even though you've bettered yourself in every field so far, you still have a ways to go. If you keep trying and making comics, you'll get better, then you can make an all new comic to show off your skills from the get-go.
I'd recommend downloading something like Paint.Net, though. I use that for motion blurs and text boxes; it makes them look better IMO.
