Great question! One major mistake is overcomplicating the design. A mistakes in logo design should be simple and memorable—think of Nike or Apple. Another issue is using too many colors or fonts, which can confuse the viewer. Also, relying too heavily on current design trends can make the logo look dated quickly. It’s better to aim for timelessness. Another mistake is not considering how the logo will look in different sizes or mediums. It should be scalable and recognizable whether it's on a business card or a billboard. Lastly, skipping proper research and not aligning the logo with the brand’s identity is a big miss. A logo should tell a story, not just look good.
