Following the scifi theme I started here:
... I came up with this.
Again, all the texturing was done in AR, using a basic grey render of a 3d model I made in another proggie.
I include the basic reference, a screenshot of a WIP and the final result. I had to scale down the final image for the forum, so it does not do justice to the original, but you get the idea.
As usual C & C's welcome.
