grrr.

I was working on some vector art in illustrator, and my dad came over to see what I was doing (this was a couple days ago). I showed him my friend in his tigger outfit, and my dad thought it was great. "People could pay you to do this stuff," he said. Then he offered me 100$ to do vector art of my family, the four of us, so he could put it in his office. I've been working on it - I finished my brother, and I put a ton of work into it, but he doesn't seem to like it, he seems to be regreting offering me the money, maybe he was just kidding. But I honestly don't think he was, and I'd love to do this project, but I'm wondering if I should charge him as much (it'll actually take a lot more time than I would consider 100, but that's because I'm a beginner). So I don't know. Grrr.
