Thank you guys as always for the encouragement, but it just don't look right still. So, for a fourth time now, I've tried again. A few learning points I've found. The stretched out wet wipe mask does not work well with rattle cans. The reason being I think is that the paint globules are too large and need to be sprayed from to far back to penetrate the smaller gaps in the web of the wet wipe, and so do not give the thin lines/web in the marble. If you get the can too close to penetrate the material it delivers far too much paint and blobs. When I tried to free hand it with the airbrush on the second time, I made all the swirls of colour angled to draw the eye to the centre of the board, they work diagonally in. That's not how marble looks, and it caught the eye more as some sort of animal print than marble. On my third try, free hand with a paint brush, wet wipe mask over it, it just looked like a mess as I simply laid the wet wipe down, minimal tension so it.
On this last try, I thought about each panel being individual rather than trying to paint all the floor as a whole. I masked the panel, stretched and tapped down the mask and used the air brush tight in to it to get the paint through it. Ahhhh, at last
*sobs, shoulders bobbing* at long, long last. I've cracked it for the look and scale again. It also marries up proper with the bases. Once all done, a gloss varnish and some oil washes. I should have done this from the start but, eh, what seemed like a short cut at the time, has been quite the opposite. Still, you live and learn.
So as not to bore you all with my same old trial and tribulation, here is a pic of something else. The walls.
