Hey James,
You are mad you know for building another 6 tiles?!

You featured in the TerrainTutors last Sunday night live vlog. He admired all that cutting!!!!
You will be blending all the tiles together with another top coat/drybrush when you've finished the final 6 yes? The road changes colour a bit between the old and the new, and the grass.

It's a nightmare trying to match existing terrain colours isn't it

Silly paints drying different colours.
Cheers
Matt
