A Harry Potter-inspired sticker with the quote 'There R17;s no need to call me R16;sir, R16; Professor.' and magical elements.

A 2D flat graphic sticker design featuring the quote: “There’s no need to call me ‘sir,’ Professor.” in bold serif lettering with a Harry Potter-inspired style. The first part of the quote is in smaller arched text on top, and the word “Professor.” is large and bold at the bottom. Include whimsical Harry Potter-themed elements: crossed wands with light spark trails at the top left corner, a white owl with a broom in the right corner, a minimal Hogwarts castle silhouette in muted purple behind the text, a small potion bottle with teal liquid on the left, a simplified Marauder’s Map scroll on the right, and a golden snitch at the bottom center. Use a color scheme of burgundy, deep gold, navy, and muted purple. All elements have bold outlines and flat colors with a transparent background, designed for use as a sticker or t-shirt graphic.
