shadows

The community here has been great in helping me find plugins and other resources I'd used on my old project, but I've discovered one more. To really sell the fact that the birds flying around were actually far off the ground, I somehow created shadows that were a few frames under them, as seen...

Why have different or no shadows? Fann the Fairy's shadow is the same width as Dwargo the Dwarf's. Is there maybe an attribute in the Actor's section that can modify the shadows? Dwarf's long beard credit @Xyphien . Increase party size credit @eivl .
