You can actually see my very first 24 Hour Comic still here on deviantart riiiight here: [link]
Keep in mind, this was done in 2005. I was like 16 or 17 and huuuuge into anime (mostly Naruto at the time, in case you can't tell from the comic), and I hadn't even figured out how to upload a .ZIP file to dA, so you have to click on each page separately
One thing I can say, though, is I sure didn't make it easy on myself for my first 24HCD comic.
Don't forget, if you want to read more of Kastle Comics, you can always check out the original dead-but-still-funny webcomic right here!
