Nearing the halfway point on animation

I'm almost half finished with my animation and so far things are going well. I am really enjoying the process for the most part and making steady progress. I am slightly concerned with the length of my project, specifically if it will be the required length. Of course, I can always add more scenes and elaborate on existing ones to make the animation longer if needed. At this point in the animation, I am also excited to add my other main character and my supporting character. Though neither of these will be as developed as the existing woman, they will play a major part in the overall story. Making their roles larger than I first anticipated will be a great way to add length as well.
I also feel that I have learned several valuable skills recently that will help me animate the remainder of the video more quickly. Being able to make progress at an increased rate will also help me to meet the length requirement. Overall, I am still rather assured in my ability to finish the work on time and meet the length requirement.
