I mix batiks with non batiks in a lot of quilts but i would not do that in a bargello unless the non batiks "read" like batiks (such as some of the Robert Kaufman Fusions or Moda Marbles or another blender)
The two prints you have inserted with no label do no flow like is needed in a Bargello. Like on the river posted they do not have the same mood or tone.
Additionally you have several colors that are extremely close in value. If you have a photo editor tool on you computer that you can switch and view your fabrics in a black and white setting you will better see. Here, I attempted to do that for you. This gives you a good idea of the light medium dark values you have. You can see fabrics 9-14 have very little change in value. And fabrics 20 and 21 don't seem to be in the correct placement for value either if you are attempting a light to dark gradation.

Edited to add #8 is a great "zinger" leave it as a fabric choice but you may need to reassign its placement.
