Hi there, I'm not sure if my style is exactly what you described, but I thought I'd give it a shot anyway. I'm a children's cartoonist and illustrator, with some samples of my work at http://www.catherineharrell.com. I have done several mascot and character designs in the past, and I can present the final version as a vector file if you'd like. Let me know if you see anything you like, and I'll see what I can do! -Catherine
