Create an embroidered patch of a Catrina in Chicano style. The Catrina should have detailed skull face makeup with bold, smooth lines, blending traditional Mexican and Chicano tattoo art elements. Her expression should be fierce yet elegant, with a mixture of roses and bandana in her hair. Use embroidery stitches in monochromatic black, white, and gray shades with subtle touches of red. The patch should have no background, focusing entirely on the intricate details of the Catrina. The stitching should be thick, giving the impression of depth and texture, typical of embroidered patches.
