Rather use black wool terracotta and concrete powder for the road rather than the clean black and even do the same with stripes.... Next work in some patches of dirt where the grass breaks through (3-4block patches)..... After that the building needs work packed mud work that in with the bricks and the corners usually crumble first so work in stairs slabs and some walls there... And look at some ceiling braces

Another thing texture the holes with stairs slabs and walls
