In the Sonic X, Sonic stands confidently in front of a large crowd. He wears his iconic blue outfit, with his arms crossed and a determined expression on his face. In the background of the picture lies an urban landscape, its many buildings illuminated in the night.
To bring this image to life, I would start by giving Sonic a pop of bright blue for his main outfit. I would choose a few primary colors for the buildings of the cityscape, like shades of red, yellow and green, to create a vivid contrast with Sonic's outfit. To further bring the image to life, I would use darker blues and purples to create shadows and lighten them with silver and pale shades of pink. Finally, I would finish up with a pop of silver along with white highlights to make Sonic stand out, and to give him an added layer of detail.
