Good job on these. However, I feel like at this scale, the cracks read as too large relative to the houses, so they look like they're on the verge of crumbling apart. I think it might be better to replace the cracks with more scale-appropriate details, such as extra windows, banners, or extra wooden beams (for what is apparently meant to look like half-timber architecture, there are very few visible wooden beams here).
Those are nice!! I love the little details and the overall structure!
Thanks for the advice, I'll take care about what you say.
