I kept working on the miniature, saturating more and more. I also started adding elements on the top, which begin to break out of the main frame.
The views are taken with a very closed angle, to intensify the feeling of saturation that happens within the miniature.
About the color issue, I talked to several print shops, and I might be able to screenprint, although timing is a bit of an issue if it has to be ready by the jury next week.
Another option I started considering is laser cutting stencils for screen printing on my own.
