We are finishing our basement and the design company suggested large paintings and I liked the idea, was curious where I could find something like this? They are huge and I haven't been able to find anything that matches. Any other recommendations for a wall like this? I'll admit I don't want to spend an insane amount of money just for this so if there is another idea I am open to it, even something that doesn't involve paintings.

Also, the design company made the dark color accent wall but didn't specify what it actual was. I am not a fan of wallpaper and I don't think paint would be rich enough so I figured a wood accent wall would be best. I have white brick accent wall on the other side so hoping to get some clarity on what I should really do there. It will also be on the long wall opposite the paintings. I didn't know if that would be "too much" or if that would be good. I simply don't have an eye for these things.
