Create an illustration of a group of five diverse characters standing side by side, designed in a flat design style. Each character should have distinct, simple geometric shapes with solid blocks of vibrant colors. The characters should feature minimal facial features, such as small eyes, simple smiles, and no intricate details, to keep the style clean and modern. The group should include a mix of different skin tones, and each character should have a unique hairstyle and outfit, ranging from casual to semi-formal. The outfits should be in bright, contrasting colors, with no patterns, to maintain the flat design aesthetic. The background should be a solid, bright color, such as light blue or yellow, providing a cheerful and welcoming atmosphere. Ensure that the overall composition is balanced, with the characters evenly spaced and standing upright, looking directly at the viewer. The mood should be friendly and inclusive, with the characters smiling subtly.
