It's cool that you remember that drawing you did. I bet if you really think hard about it, you'll remember how your hand cramped up while doing it. I hate that about pointillism. It also gives me an anxious feeling when creating it. No clue. I'm weird.. what else can I say? lol.
Do you still have the drawing?
I might, I don't really know for sure. If I do it is probably buried in a file cabinet somewhere. I was young back then, the cramps probably didn't even phase me!
