In 2019 a friend and I both backed a Kickstarter campaign for jungle themed ruins terrain from a Polish company called Archon Studio. Both of us received our pledges last year, but neither of us got around to assembling or painting it for a variety of reasons. Over a couple weeks we each assembled our respective packs and last weekend we got together for a work day to get started painting the collective terrain. Over about five hours we applied a base coat with various colors from rattle cans, namely teal/aqua blue, violet, orange, and a grey/black. From there sponged all of the pieces with cream and yellow ocher, then drybrushed again with cream. To tint everything and add more interest we then applied unthinned oil paint over the pieces. The oil colors we used were burnt sienna, raw umber, burnt umber, paynes grey, olive green, phthalo green, and magenta. Once the oils were down we used paper towels with some white spirits to wipe away the excess and blend the colors together where necessary.
Here are some assembled pieces prior to any paint going on.

Next a picture of the pieces after the rattle can treatment.

Here they are during the sponge and drybrushing phase.

Here is a more detailed view of a piece after sponge and drybrush work.

Lastly, here is a piece after the oil paint application and subsequent wiping off.

On the day we got together we were able to complete about half of the project through the oil paint step. Of course all pieces still need a generous treatment of moss and other vegetation. I will update with some more photos when we've achieved that step. Over all we are both really happy with how they are starting to turn out, especially with no precision brush work involved.
