**Design Breakdown for a Modified Off-Road Vehicle:**

1. **Body Shape:**
   - Retain the boxy, rugged silhouette for off-road durability.
   - Alter the roofline to feature a more aerodynamic shape without the tent.

2. **Color Scheme:**
   - Change the exterior color to a matte dark blue instead of olive green.

3. **Wheels:**
   - Use a multi-spoke design instead of solid black wheels.
   - Increase the wheel size for a more aggressive stance.

4. **Bumpers:**
   - Simplify the front bumper design, removing the grill protection.
   - Opt for a sleek, integrated LED light bar instead of the prominent attachment.

5. **Windows:**
   - Adjust the window tint to a lighter shade for a more modern appearance.

6. **Lighting:**
   - Replace circular headlights with rectangular, LED-focused lights to give it a contemporary look.

7. **Details:**
   - Remove all brand labels and identifiers for a neutral presentation.

8. **Accessories:**
   - Replace the rooftop tent with a sporty luggage rack for additional storage options.

This design retains the rugged utility while offering a fresh, unique appearance.
