To draw Mickey Mouse step-by-step, start by sketching his iconic ears with gentle, curved lines. Refine the shape of the ears into a perfect circle, making sure they are slightly tilted upwards. Next, move on to the face, drawing two small circles for the eyes and a tiny oval for the nose. Add some personality to Mickey's expression by smudging the eyes slightly and adding a few gentle wrinkles around the mouth.
For the body, draw a rough outline of a circle with an oval shape attached to it. Refine the shape into Mickey's signature pose, with his arms tucked in close to his body and his legs splayed outwards. Add some texture to the fur by drawing short, curved lines that follow the contours of the body.
Finally, add some details such as gloves, shoes, and a bow tie using thin lines and simple shapes. Don't worry too much about proportions or accuracy - Mickey's charm lies in his simplicity and recognizability.
