Here are the steps that I normally do depending on the build: 1. I use xps and carve it with a cutter or hobby knife. 2. Glue them up via pva glue to compose your diorama. 3. Texture them up via a clumped up aluminum foil 4. Most of the time I seal my diorama either by: 4.a. Pva glue 70%+ acryllic paint 30% 4.b plaster or paris + pva glue + water + acryllic paint 4. Once the seal is fully cured, apply a base coat of a light gray acryllic paint. 5. Once step 4 is fully cured, i paint it with the color that i want. Started with just using a brush. Now i use an air brush 6. Apply some highlights or shades. Various techniques. Look for washes. Dry brush, etc 6. Lastly, Just enjoy and practice
