Logo integration and marker overlay effect
Prompt
The first image is the illustration. The second image contains a logo design on a black background. Place the logo in the largest, cleanest empty area of the illustration—the area with the fewest lines, shapes, and visual elements. Replicate the logo from the second image exactly as it is. Render it with bold hand-drawn brushstrokes, creating an effect as if signed directly on the surface with a thick marker. Allow the logo to slightly overflow the empty area, extending into adjacent illustration content. Color rule: The logo color must always contrast with the background beneath it. Use dark lines on light backgrounds, and light lines on dark backgrounds. If the logo crosses multiple background tones, switch colors mid-stroke. Never let the logo blend with surrounding colors. Do not modify the illustration in any other way. Be sure to fully preserve all original colors, lines, and composition.
