Some tracks seem jagged, but maybe this is a rendering issue restricted to the .png image, anyway I think you could to thicken some tracks a little, so the board does not appear so vulnerable if the assembly is done by hand or if you have to rework by replacing components.
In addition, I would move away some components from the edge of the board, as well as ensure a keepout the ground plane from the contourn so that it does not short-circuit with the chassis of equipment or any other electrically cherged part.
