IMO your choices don't have any cohesion. Since you just put the wallpaper in and I'm assuming you don't want to change it again, I would design from that. You can choose one of the colors from the wallpaper and use that for the rug. I like the red color of the Persian, but I do think that it is too busy so it is competing with the wallpaper.

the wallpaper is fun... maybe have a solid print rug to help complement the wallpaper.

Can you put the tapestry and the Persian rug in another room? They both clash with the light-hearted wallpaper. The table is fine. A solid rug matching one of the colors in the wallpaper would be more pleasing...dark enough to hide a little entry dirt.

I like all the items you have chosen but I don't like them together. The wallpaper being the most difficult to change, I would work with that. Pull a color from the paper and find a solid rug to match. I would relocate the tapestry to another space. I like the table there just decorate it again with colors from the paper and stay away from a floral design on anything. If you want to introduce a pattern I would suggest a plaid or stripe. I think a mirror above and a lamp on the table would be nice.
