ok well its done, it's just drying at the moment so i can't get the final pictures until i can stand it up.

So this is how i do my backgrounds

1st black was applied, i did several coats to try and cover every tiny spot of grout i could see

2nd i sponged on a dark grey color. These two pictures are how it looks after the grey. This is why i like to base coat in black, i think it really makes the grey show up. The pictures don't do it justice, you need to see it under 6500k lights to really see how the paint pops on this





Now this is not how it looks finished. The last thing i did was used a light grey to dry brush over the rocks. Really brings out detail and brings the rocks to life. You'll have to wait a few more minutes until its dry enough for me to stand it up and snap some pics
