Many thanks to all. Not bad as a first try, but I need to do the walls less tall, less angled, shorter and deeper parapets. And add stairs... And of course then I need some outer works - either tenailles and counterguards, or demilunes and arrows. Maybe a ravelin...connected with a bridge to a more elaborate gate..
