Here is the result guys!
I spray painted it Skull White.
Used watered down Mourfang Brown as a base for the soil.
Bestial Brown (watered down) for the ruin.
Then it was dry, I did the same process without water.
I drybrushed the ruin with Tausept Ochre then drybrushed the soil with Snakebite Leather.
I heavily watered down a mix of Abbadon Black and little dot of Khemri Brown. I washed the whole thing.
Went over with the drybrush again with the same above. When everything was dry I took Bleached Bone and highlighted the soil and the ruin, then used Longbeard Grey on the edges just to make it a little more sharp.
And finished of with some metal bits and grass with my own mix. (from GW and an old train company thingy I bought from work a long time ago.)
I green stuffed a triscale(spellcheck on that plz?) with a wire support, then it's dry I will paint it like a vine so it look's like the plant has climbed.
Mr Skeleton will be put down at the debris :)
