Create a polished character expression sheet for the same Devon Rex cat mascot from the reference concept: warm beige-gray short curly fur, oversized bat-like ears, amber eyes, coral-orange neckerchief, mint-green star badge. Show six separate cute bust portraits in a clean 2x3 grid on a warm cream background: happy laughing, curious tilted head, surprised, sleepy, proud wink, slightly grumpy. Consistent character design, bold clean outlines, flat vector-like colors, premium Chinese mascot IP style, clear facial expressions, no text, no watermark.
