I managed to finally finish my animation, with the sound added. I took time to create the soundtrack using Adobe audition and some royalty free sounds from ZapSplat.

During the process, I took into account the animation principles for my final. I used exaggeration a lot so that I could better convey my story. Using the principles enabled me to create a concise and clear story whilst keeping the animation smooth.
