That looks well effective, nice one! Gonna be selling or just multiple casts for yourself?
I may well have some casts spare once I get going.
At the moment this is going to be very much a "project" where I hone my model making skills as well as those of casting. My pump is waiting for me at the post office!
I have more plans for these pieces though. One wall isn't enough on it's own so I am currently sculpting another of this length and working on 4 wall posts.
At this point I am happy to take some suggestions as well.
