Nice work Victor I like the style of that blade. & Welcome To Iforge Iron
I look forward to seeing more of your work.
To get a better picture of your hamon, try these 2 things that help me.
# 1 bright but diffused indirect lighting from several sources ( no bare bulbs or the sun reflecting off the blade to wash out the hamon ) also if you must take a photo using a flash, tape or hold a peice of white tissue paper or a dryer sheet over the flash bulb.
# 2 Reflect the color black into the blade ( a peice of black cardboard or black cloth held 12- 18 inches above the blade) so the reflection shown is dark. This helps highlight the whiteness of hamon.
Other than that its just Polish, Polish, Polish then Re- polish
Hope this helps.
