Design Breakdown:

1. **Color Scheme**: Use a bright yellow top with contrasting dark blue sleeves and pants. Keep the bright yellow as the primary color for visibility, making it suitable for outdoor sports.

2. **Jersey Style**: Change the collar from a traditional shirt collar to a modern, angled design. Remove any country references or logos, but add abstract geometric patterns for visual interest.

3. **Gloves**: Opt for a pair of vibrant orange gloves, similar in style but without brand logos. Make the gloves more padded for better grip and protection.

4. **Headwear**: Replace the cap with a wide-brimmed hat for sun protection, retaining the bright color but adding vents for breathability.

5. **Pants**: Modify the pants to feature side stripes in a contrasting color, such as dark green, for a stylish look. Ensure they are functional and flexible for sports activity.

6. **Footwear**: Choose sturdy black shoes with brighter accents, focusing on comfort and performance features suited for athletic movement.

7. **Accessories**: Eliminate any visible branding and incorporate a simple wristband or sweatband in a matching color to enhance the sporty appearance.

8. **Background and Setting**: Soften the crowd colors to maintain focus on the athlete, possibly blurring the audience to create a dynamic, action-oriented atmosphere. 

This design maintains the spirit of sporty athletic wear while being unique and original.
