% Randomly perturb the shape slightly to add more uniqueness

y = y + (rand(size(y)) - 0.5) * 0.02; % Small random perturbation in y

% Random position and rotation

y_shift = rand() * 5 - f * 0.05; % Shift leaves down over time

rotation_angle = rand() * 360;

% Random color (autumn-like colors)

leaf_color = [0.5 + 0.5*rand(), 0.25 + 0.5*rand(), 0]; % Shades of orange/brown

% Draw the leaf with random position, rotation, and color

leaf = fill(x_shift + x, y_shift + y, leaf_color, 'FaceAlpha', 0.7, 'LineWidth', 1);
