He's alive!
Of course you cringed. I cringe at the stuff I see in my sketchbooks when I was 14. I'm sure I'll cringe at the stuff I'm doing now eight years from now.
I read the whole thing.
From what I remember it didn't feel like a Pizza Cats story at all. I liked it okay and read the whole thing to the end (keeping my interest that long is a feat in itself) but SPC is a very silly show. KNT is a slightly more deadpan very silly show. Crimson Dawn was super serious. It might have fit in better as a fanfic for another series, or as an original short story. And Jonas...Jonas felt a bit too self insert "I put myself in a fanfic! I'm awesome!" quality to it. This was about seven years ago, I hope I'm remembering this stuff right.
Have you been writing for fun since then? You should if you've got the time at all.
