Marc - I like the look of the cobblestone. For some colour ideas, have you done a google image search for the particular country or maybe even the city?
Andy - the weather effects are looking right on. Figures look great - I know the diagrams didn't show this, but being a winter setting, adding a hint of the same warm red to the tips of their noses would work well here.
Dave - wish I had some answers for your questions... but have to say what you've done so far is looking rather swell.
So this weekend was able to finish construction of the turret.
First time trying weld beads, so I gave Fine Archer's product a go. The set was a variety of sizes - no set scale, your choice on the width that you deem fits best.
They have an instructional video on youtube for the application of these. It is basically resin on decal film, and is applied with Micro Sol setting solution. I tried doing the bead around the copula first, but could not get it to curve. So opted for the stretched sprue here.
The turret itself faired no better. The straight stretches worked great. The curved portions, even though not as acute, was problematic. I tried adding future, waiting for it to become tacky before laying down the resin, but even this did not help. I eventually had to cut the bead into 2-3mm segments. I don't know how they did in the video, maybe it being winter here, room temperature/humidity played a factor.

Jack
