Can we see pictures of the entire room. It is hard to give any type of advice, without seeing room size and placement. I do have one comment though. Move the tv from where it is covering a window, and once design has been decided on, but a nice tv stand to put it on. Also, all the things on your wall, are hung way too high and look like they could be better sized for where they are hanging.

I agree with cat_ky. Post more photos, relocate the television, and lower the artwork. Also if the table is in good condition, I would remove the tablecloth.

Church basement or a home, there has to be a better place to put a TV than hanging in front of a window. Please start with that first. It just spells danger to me.

Yes, certainly! As the others said, it'd be easier for us to help you with more photos. I'd start with the position of the TV, maybe it works for you but based on the pics, it seems like it's a very difficult place. I'd also refrain from putting furniture against the wall. I hope we can do more to help you!
