Made my own Ariel and Flounder characters in Spine. Unofficial of course I just made this for fun. Also I ended up watching The Little Mermaid like 5 times in the course of making these. Scenes were composited in and using VFX from After Effects. Please enjoy the serene visuals and pleasing soundscape. One day I'll make a 10 minute version of the Ariel and Flounder hanging out by the sea. My laptop isn't powerful enough to edit and render it in After Effects unfortunately.
By the way, Serenity by the sea's background and scenery was entirely created using After Effects.
