That's a great looking layout. I'm guessing you had to paint the terrain, any tips on the method used?
After much faffing around, trying different techniques, I have settled on doing some bits with ink, using a sharpie and painting some bits.
Some bits had ben sprayed grey, but that takes too long and the weather has to be right, so I don't think I will do that anymore.
The metal is done with a Gun Metal paint straight onto the MDF.
I use a black sharpie to do some of the edges and the ladder rungs.
For most other areas, I am now using ink. The trick is to wipe the MDF first with a warm damp cloth to get rid of any sticky stuff. I then ink the components before building.
Even the railings are done with a black/grey ink and it comes up good after a bit of drybrushing.
