I'm quite happy the way it turned out, by far the most difficult mod I have done. It is made very typical to my other mods; hand sculpted, then made to a mauld, cast with a plastic resin, and finally hand painted. For the most part the walls are 1/4" thick, but very a little.
I am thinking $400 CAN for the full mod. (Castle and Calderon) $120 CAN for just the colderon.
