Just came back from my parents' house for the first time in about seven months and they let me borrow back the TMNT scribbles I did as a kid. When I was about 10-12 I wrote a bunch of TMNT comics, then around 16 I wrote a few more (and those, actually, surprisingly, look pretty good even now... will post those later).
TMNT #0 (drawn when I was like 12, then touched up a bit when I was in junior high, the bubbles rewritten to make it a sequel to the movies)
TMNT #1 (also drawn when I was about 12, then touched up wayyy later in junior high, also with some added pages from around then... rewrote all the dialogue bubbles at that time too, mostly with the intent of making it a sequel to the movies, though now I kinda wish I hadn't)
