This group of superheroes, drawn against the backdrop of a bustling city street, is standing close together with unwavering determination and focus. The range of shapes and sizes, in addition to the different colored skin and hair of each hero, gives the scene a sense of depth and dynamism. All of them have serious expressions on their faces as they gaze towards the sky, as if they have finally come face to face with the challenge they have been preparing for. To color this image, shades of blue and grey, red and yellow should all feature to capture the intense energy and determination in the air. The heroes could be brought to life with a range of warm oranges and reds for the skin tones, and bright pinks, blues and purples for the costumes. To finish the picture, a few hints of white, black and silver should be used to bring out the subtle details.
