Once I finish painting all the pieces for this terrain set I'll add some snow effect to the edges of each base to help them blend in to the mat and tie the whole theme together.
The first piece I built for this set is the landing pad. It's primarily made out of Mantic Battlefields panels with a MDF hexagon for the landing pad. I detailed it out with some Games Workshop bits from my bits box and other random resin pieces I've made copies of over the years. (I've found that if I find a cool bit its best to make a silicone mold of it because I'll inevitably forget where it came from or be unable to track down more in the future.)
After laying out the panels in a rough idea of what I wanted to do I used a jigsaw to cut a piece of MDF that I textured previously with drywall tape and cardstock. I then glued pink foam to the base and used a razor knife to carve out the shapes I wanted. From there it's just a matter of gluing the parts in place and painting.
I base coat everything with a Behr paint and primer that I had the guys at Home depot match to the hobby paint I use. The wash is a Minwax water based stain that I thin down 2 parts water to 1 part stain. A base coat, dry brush and wash gets this piece to a playable state quickly and I'll detail it out after I've tested it in game to be sure nothing needs to change.
