Uncertainty ?

I halfway finished the tile in the bedroom. And I’m not in love with it. I left it over night and revisited it and I still don’t like it. I feel like to like it I will need to add grout, but I don’t think I want to do all of that work to possibly still not like the outcome. I’m really thinking about taking it out and trying a different tile in the bedroom.

The main problem is that the original tile was very thick making it difficult to cut straight. So all the planks are uneven. To me it looks sloppy. Which I don’t like.
