Create a realistic anime-style image featuring two young men at the beach

Create a realistic anime-style image featuring two young men at the beach. Both should have well-defined, six-pack abs. The character in the front has short, tousled brown hair and green eyes, while the character behind him has black hair and blue eyes. They are standing close together, with the taller one behind the shorter one, and the shorter one making a gesture with his hand. Both are wearing swim trunks, with the front character in green and the back character in blue and white striped trunks. The overall atmosphere should be casual and friendly.
