In a fantastically surreal cartoon setting inspired by the aforementioned artists, we open on a vibrant, technicolor dreamscape resembling Winsor McCay's "Little Nemo in Slumberland." The background is a vivid, kaleidoscopic sky where fluffy clouds take the form of oversized speech bubbles. The largest bubble in the center reads, "Good Luck, Mitch!" in bold, swirling letters formed from rainbow-colored tendrils that echo the Pride flag.

Front and center, we see a lively parade of drag queens dressed in outlandishly glamorous costumes inspired by R. Crumb's exaggerated styles. Each queen is on stilts and their sequined, feathered, and bedazzled outfits glimmer under the whimsical sunlight. They are sashaying down a surreal pathway made of glowing, pastel cobblestones that twist and turn like a Gary Larson comic.

To the left, Rita Ora is depicted as a celestial figure floating above, much like an ethereal character from an Osamu Tezuka manga. She is wearing a golden gown that flows seamlessly into the colors of the Pride flag. Rita is holding a microphone that extends down to the parade below, sending musical notes that look like colorful butterflies fluttering in the air, reminiscent of a scene from Hergé's Tintin adventures.

On the right, there's a giant, intricately decorated hot air balloon with "Goodbye, Mitch!" scrawled in big, playful letters. The balloon is manned by characters that look like a cross between Peanuts and Calvin and Hobbes characters – whimsical, with large expressive eyes and round faces. The balloon basket is overflowing with various good luck charms, from four-leaf clovers to horseshoes, all drawn with the meticulous detail seen in Art Spiegelman's work.

In the foreground, near the pathway, is a quirky, whimsical tree with branches that curl and spiral like the imaginative landscapes of Bill Watterson. The tree is adorned with small flags bearing messages of good luck in different languages. The leaves of the tree are painted in a gradient of colors, creating a magical rainbow effect.

Finally, scattered throughout the scene are smaller details that add to the whimsical farewell atmosphere – tiny animated stars with smiling faces, a snail with a monocle and top hat, and a few balloons floating up into the sky, all reminiscent of the fun and absurdity found in Will Eisner's works.

This surreal, vibrant scene is a farewell like no other, combining elements of pride, celebration, and well-wishing in a truly unique and imaginative way, all while celebrating Mitch’s journey onward.
