Here is one more illustration by Naime Pakniyat that commemorates the release of Fit Arabic by @Sahar !

As @dogray explains, this illustration turns the theme of spring inward— “the images live inside the letterforms and reflect on other ways Iranians have celebrated the arrival of spring: a celebration, a fresh start, a feast.”

This connects to an essential aspect of Fit’s design—“Both the interior and exterior are essential for the font to be what it is.”
