Nice start... now the real work begins. We get to see a lot of good-looking bots, and bots that people have put a lot of work into as far as appearance goes, but they don't attract an audience, or keep visitors chatting very long, because of errors in the AIML and an inability to follow the conversation. People visit chatbots because they want to chat.
As you're working on animation, you might also work on some of the replies, or the way Homer answers. Have a look at the Pandorabots Corrections Section and see what you might discover about how your bot is currently "misunderstanding" or replying in an erroneous way.
Best of luck, nice beginning. Keep us posted on any advancements.
