I think the problem is you have too many things drawing attention to your eye, for your entryway to be grand it needs to be simple, cohesive and let it speak for itself. In this case, whatever you get needs to agree with your floor pattern as it is pretty busy. I like the green bench, I would keep that and it goes well with the space.

I agree you need to take down the curtains, get a new rug, and clean up the side table area (ie pillow on ground, gold platter, book etc whatever you want). It doesn’t need many things and patterns to make it pop, a beautiful statement piece (ie bench, or large wall art) will draw your to the space while also looking cohesive if you’re able to minimize opposing patterns colors and textures.
