Thank you! By jaw I just meant transforming the part of image to move the character’s jaw up or down. I was switching between frames to see how much to adjust it but i think you might be right, I did not deselect it hence it might have been showing in other frames that way.
I did remember one thing as far as coloring goes. Clip studio paint has this downloadable fill tool, which works like this. You mark your lineart layer as reference layer. And as long as there are no gaps (some level of adjustment is available) you use a lasso fill tool to quickly color areas in just by drawing around them, and when you let go it fills it in.
