Ok here we go again. Since I´ll update this skin in the near future quite often with new pictures etc. the best way not to spam the screenshots and the workshop is to open a discussion where I´ll post the updates.
So since the last update my main focus was on the engravings (again). In my opinion they looked not like engravings but more like someone glued them on the metal. So I tried different approaches to get a satisfactory result:

Finally I came up with this one:

Oh and I reworked the pattern so it looks now more detailed then before.
Hope you like it. Next step will be finding three different color schemes (again).
