The pics are very good and informative.

The bevel is all one color, thats good, if you had 2 different angles on the bevel they would reflect the light differently and show up as 2 colors.

The scratch pattern extends for the full width of the bevel, I hope it does for the full lengthas well.

The scratch pattern is uniform. There is no cross hatching visible, another good sign.

The scratches seem kinda deep for an 8K, that simply reflects that you have not completely replaced the scratches from the 1K with a set of 4K scratches and then replaced the 4k with a set of 8k scratches. Once you use the 4K you will see the difference.

Your doing well, keep at it, but also get a razor honed by someone from the SRP to act as "standard".

Just my $.02,
