Honestly, that's worse.
I think the black/yellow bricks you're trying to copy don't really work in Blockland because of the scale. The lego ones are decals, and have a finer level of detail than bricks can recreate. You either need small bricks, or you need a custom print.
What you have now doesn't look like the plaster that it's supposed to represent.
They look like out of place windows, with lights shining through.
I know you're imitating the old lego bricks, but perhaps try using a very ligh grey colour instead of yellow, to represent the plaster. Because the old lego bricks are an unrealistic colour. It was an odd choice for them.
And the light grey bricks really clash against the black. You're trying to make it look like a brick wall, with different coloured bricks, but those two colours are too contrasting.
