Turns out, working at 4k with as many layers as I'm used to using for static image drawings isn't a good idea. I've had to dial back and rework how I approach the animation process.
Things are back on track now, but I took some time to rework the kissing panel as well since I wasn't happy with the colors not matching the portrait, and more. The rimming panel will take awhile longer to splice up so I can continue working, but hopefully this'll be done before March is through.
