Wanted to practise construction a bit by copying a screengrab, took one from Princess and the Frog since I obviously love that movie! (I wouldn't recommend copying this exact frame for practise though since it's pretty cluttered around the frogs)
Used a ballpoint pen since that way you can't erase your lines so everything's visible in the end. It has some errors in it, for instance I didn't really construct Louis' body at all (see how the tail goes nowhere), and there's quite a difference between the distance of his mouth and Tiana in the original and the drawing. Bla bla bla

Here's some more ballpoint stuff
