I had a lot of fun with this, although at times it was frustrating. Probably the biggest thing I’ve learnt from this project is that not only are excessively large image sizes unnecessary, my computer hates them, especially once you bring in multiple layers. Most of the grief this gave me was because my PC had to deal with a 10000 by 7000 image with about 30 layers. Sorry computer! I promise I’ll never to do that to you again! (Spoiler: I probably will.)
Other than that, some parts – specifically the stairs and banisters in the foreground -would have benefited from me using 3-point perspective, instead of shoehorning everything into 2-point. Maybe next time.
