TT Combat used to do various castle elements, a keep and battlements etc. Well worth a look at all their stuff if they're not on your radar. Also, TEMU have some great MDF and plastic models, I saw a whole medieval village for less than £30, but they didn't seem certain of the scale.
That fortress does look good and I like the idea of matt varnishing it before painting, I've had the Devils own job painting mdf in the past, it didn't occur to me to think of this, so thank you for that. I like the T shirt, those were 2 very good films I recall his assistant was called Vulnavia.
