A bit, I think, though it is improved. It's hard to convey so much detail on images with so little space - that's why the grass is good. For GBC and NES, making full on grass blades every frame would be awkward.
Here's an edit of what I thought. I pushed a brick out to make it less monotonous, though this shouldn't be done ALL of the time like below - it should be a different tile that you can use to break it up. The bricks seemed a bit too small to make actual highlights, though it might be possible and better-looking to do so. I also added some lighting that just swaps the colors - what is the dark area of the 'normal' brick is the main area of the brick on the dark side. Black becomes its shadow color.
Anyway, I just edited the main bricks and the doorway.
EDIT: Crud, I forgot to shade the right single-width roof tile.
Anyway, that's just my thought on it. It's a cool tile-set. I like it a lot.
