How can I improve this crate model I made?

[ShotWasValid (Wurdgen)]

I made this crate but I think that it is basic and I want to add more detail but I just don’t know what to add.
(The crate is the same on all sides)

Maybe an arc in each corner Part that follows around the center circle radius with a contrasting neon colour?

If you’re modeling in blender, try adding a small slight bevel on each edge. It’s a tiny addition that makes it look much more detailed.
