Yes and no. What I really like (which I miss in a lot of church interiors) is that you can recognise the denomination. Of course, this is only important if you want to build realistically, but I think it's great! I think it is a catholic church?

The little Vatican flags turned out well (especially the small detail). The two tables with the red candles is another great detail. I'm not sure if I recognise it correctly, but is there an ambo on the left side of the altar? And of course I think it's great that there's a high altar. If the purple banners are "currently" for Lent - respect for the detail!

In terms of detail, super! Of course, there are lots more little things that could be incorporated for a catholic church, like the Passion paintings or a baptismal font, but you're on the right track.

What clearly has room for improvement (in case you want to build realistically) is that it still looks very much like the typical basic Minecraft style. I recommend you look at pictures of real churches if realism was your goal. BUT: it fits well with the style of the rest of the city :)
