These are for the hexagonal domes, the Brown and the Yellow domes. There is so much you can do with hexagons! Hexagons seem to be the number one geometrical form that is done in freehand miniature painting architectural geometry.
Start by drawing freehand hexagons down the central line of your dome. This is the Brown dome on a tea stain background.
2. Then draw freehand hexagons down either side. It should be obvious where these should go, in the gaps and in between the central ones.
Note: If you wanted to do it properly you could either draw them on isometric paper first or draw isometric dots on your page first. I think it's good practice also to do things freehand as then you intuitively understand how things fit together. Both ways are good.
3. Fill the whole dome!
4. This is for the Yellow, final dome - just to show how the hexagon size originated: it's actually based on the dome proportions itself. Note how the size is determined from the very apex of the dome.
5. Back to the Brown dome. Made it a bit more interesting by overlapping another set of hexagons over the first, to get a star shape or the classic cube all over. Lots of sub patterns can be generated from this grid or you could keep it simple, and you can decide later.
6. This was a bit rushed while talking animatedly on the phone! Inking in freehand (all was done freehand). Some of the wobbliness can be corrected during the colour fill. Avoid heated phone discussions for the final outline ;-)
7. Finally, for the Yellow and last dome, a simple hexagonal grid inked in walnut ink - since yellow is warm, the saffron stain is warm ( you could use turmeric or pomegranate or others... lots of dyes are yellow) - and we'll use gold paint on this dome too and walnut is warm.
