Based on the answers provided, the following corrections need to be made to the 3D object:

1. Adjust the proportions of the "L" shape so that the horizontal section is significantly smaller than the vertical section. This can be achieved by reducing the length of the horizontal section or increasing the length of the vertical section.

2. Modify the vertical section of the "L" shape to be slightly curved. This can be done by adding a subtle curve to the vertical section while maintaining its overall straight appearance.
