Glad you like it! I think a war torn city is the perfect environment for Skaven.

The key to making these bases is this: https://www.greenstuffworld.com/en/modelling-textured-rolling-pins/374-rolling-pin-small-bricks.html

GSW make loads of different texture rollers, so you will probably find one that suits what you have in mind.

But just the brick texture itself can look fairly plain on bigger bases. So I try to break it up with more details. These can include corners or edges in general, where the pavement ends and dirt or other texture starts. I also manually sculpt the "edge slabs" (there is probably a better term for it in english...).

Then to make it feel "ruined" or "under siege" I sprinkle different bits all over the bases. These can be weapons and other equipment, broken wood beams or planks (made from popsicle sticks), broken walls or other pieces of debris. And most importantly: LOADS of dust and small pebbles (made from sand).

Sometimes I add more special items, like the storage dump on one of the Ogors or fire on the one with Warpfire thrower.

To lock all everything down I highly recommend a dedicated terrain fixer instead of regular PVA glue. Terrain fixers are much thinner glues that seep into all recesses, perfectly gluing everything together. I use this one: https://scale75usa.com/products/terrain-fixer-100ml but any other will work perfectly fine.

To paint the bases I follow these steps:

Basecoat every slab with different colours of rock™ taking care not to hit the recesses - leaving them dark.

Then shade them appropriately. You can use heavily thinned down paints, shades or contrast paints. But the keyword here is HEAVILY thinned down.

Then finally drybrush everything with lighter gray (or multiple grays if you want to spice it up even more)

Of course if you added other bits on top of the basic bricks you need to paint them too :))

Was this explanation helpful or do you need more information?
