Create a highly detailed black and white vector illustration of two cute squirrels facing each other nose-to-nose on a wooden branch. The squirrels should be sitting upright with their bushy tails curved upward. Draw intricate fur texture using fine parallel lines and cross-hatching techniques. The squirrels should have large expressive eyes looking at each other, small rounded ears with tufts, and delicate paws holding the branch. The wooden branch should show realistic bark texture with cracks and grooves. The entire composition should be in monochrome black ink style on a beige/cream background, resembling a wood engraving or woodcut print. Use stippling and line work to create depth and dimension. The style should be reminiscent of vintage natural history illustrations with extremely fine detail work
