The before is good, but the after is Lucas quality. You'd get a green stamp.
As for beveling, here's an example. Imagine these are the cross sections of cylinders just before lathing....
The first uses the least splines as it's just a sharp edge where the spline corner is peaked.
The second uses two cps to contain a fillet (curved edge) made by adjusting the magnitude of the corner spline....which is unpeaked.
The third is a filet where three peaked splines meet producing a flat edge at the corner.
The advantages of two and three are that a specular highlight is produced at the corner making it seem more realistic. Because in reality, every corner is worn and not at perfect right angles.
