What my Castle Black build will look like

I'm not the best art student in the world, in fact I only took art for a term in Year 9, so it would be best if I didn't scar your eyes with my terrible drawing. I have, however found many artists interpretations of Castle Black and the Wall, also some images from the show, so I will be using them as a guide for my build. Although, I can attempt a rough plan of what the build will look like, if that is needed.
