To start, these pieces were were both made out mostly out of insulation foam using a hobby knife as needed. The stairs were cut from foamcore from the dollar store & the stair walls were cut from a higher grade foamboard from the hobby shop so it was a bit thicker and hot glued together. A corresponding stair well was cut from the pyramid shape & the stair case was inserted.
Then random stones were pushed in. I just used the tip of my pen, but any hard/flat stick-ish thing would work.
They were then painted with a dark brown base coat then used a "dry sponge" technique to paint on lighter browns & tans. Using a paintbrush, I dabbed PVA in some nooks & pressed on small patches of green flock.
For the spawning pool, I painted an extra lizard to hang out & give some movement to the water. An extra chunk of foam was cut & put in the bottom of the spawning pool to help fill up space. I cut down into the base for the lizard foot & tail too look like he was half submerged.
The water was added in a few layers. The first layer I mixed the 2 part resin as directed. Before pouring, I added 1 drop of dark green wash & stirred briefly. I did NOT mix in fully to have an even tone throughout. After the first layer was dry, I mixed the resin & added a drop of a turquoise paint, stirred briefly, and poured on top. This gives some depth without using a lot of expensive product.
To make the surface of the water disturbed as if the lizard was moving, I used a high gloss medium to add the waves. It was easier to get the medium to stay standing as it dried a bit and became tacky. White paint was added to the tips as I went to make it look foamy.
