Don't use a cartoon brand mascot to promote a luxury product or highly expensive service.
Posters and fliers: Professional grade images can really enhance posters and flyers that advertise holiday parties and other events.
Do have a professional cartoonist/graphic designer develop it for you. There are many fine nuances that go into a well-designed cartoon brand mascot. What looks good on the sketchpad may not look good when it's reduced down to fit on a business card. A cartoon brand mascot may need to look good on a computer screen, embroidered on a shirt, etched on a pen, printed on a business card or blown up on a billboard. A good designer knows how to use the proper line weights; colors and shading that reproduce and hold their integrity over a wide array of applications.
