OK...here we go..finally got around to actually doing some work on this bad boy.
And boy, did I make headway!
So here is where the project stands right now:
Here is the final coat of true Tapecrete. Notice it is white as compared to the acrylic concrete I used for the first coats. This stuff has a very short working time, so you have to move quickly before it dries.
Here is the first few coats of paint. Same brand as I always use, Liquitex BASICS Acrylic. Some Black, a bit or raw umber, some burnt umber, and some white.
After a few hours of work, and a ton of dry brushing and sponge painting, here is the finished paint.
Then I completed the frame. After careful consideration, I made a few more minor changes to give the finished project more of a Zoo Enclosure look. (Note: the enclosure is laying on its back)
And here we have a size comparison of the frame and the bedrock base/waterfall. The open areas on the floor will be the water feature. the open areas on the walls will be a coir mat covered with tons of live plants.
(The frame is still laying on its back, the rocks are upright. I did not realize this till I started writing this post...
