Hello Everybody.
Thanks very much for the kind comments.
I will of course comply in full with the requests of the online community and answer questions.
The quarry is made from cardboard ceiling tiles I scavenged from a skip. They tear very easily with a nice jagged edge or cut with a craft knife to give a crisp finish. They then need to be PVAed to harden them. Grey paint and dry brushed in lighter grey. I used 2 colours of builders sand which I left unpainted. The inside of the base is, as a couple of people guessed, a two tier cupcake stand bought from Ebay, I left the green protective plastic on the lower level as it gave a nice federation green finish.
The furniture and equipment in the base is from Copplestone and Antenocitis.
The dome I brought from a craft store.
I love the Crooked Dice Blakes 7 figures. They have hinted that they will be making more for the range, Mutoids, Scientists, officers and such, so I'll have some staff for the lower level of the base.
Anyway here are more pictures.
