Please generate an image suitable for an Instagram announcement for the grand opening of 'Espetinho do Indião e Ni'. The image should convey the savory allure of grilled skewers using a muted color palette that harmonizes with an existing logo featuring warm tones of orange, red, and brown. There should be a subtle background that suggests a cozy, inviting barbecue ambiance with understated flames or smoky hints, enhancing the focus on the skewers. Overlay the image with the text 'Aguardem... Inauguração do Espetinho do Indião e Ni' in a sophisticated, modern font that matches the upscale and refined style of the logo. Aim for an aesthetic that strikes a balance between rustic charm and urban chic, perfect for enticing future patrons
