Create a detailed collage that symbolizes the concept of 'Goals'. The collage should include various imagery that typically signifies achievement or aspirations. It might consist of peak of a mountain symbolizing reaching the height, a finish line indicating completion of a race or task, arrows hitting the bullseye on a target to represent precision and accuracy, stepping stones leading to a glowing entrance in a dark forest to depict a pathway to success, and a ladder leading to the sky to symbolize the journey of advancement. Variations in colors, textures, and sizes should be applied to make the collage visually appealing and complex.
