No matter what the question, the answer to anything that starts "do I have to" is NO. You can do this project however you want! Follow your flights of imagination -- if you fall in love with a particular penguin that you've created and want to just paint pictures of penguins for the rest of the month, then let's see those penguins. We're hoping to create a huge flock of amazing bird inspiration and have put together a list for those of you that want a list, but we'd also love to encourage you to follow those sparks of creativity wherever they lead, even if it has nothing to do with the prompt list we set up.
