You have a fairly rigid, orderly layout: image divided at horizontal and vertical center lines, text straight and centered. On the other hand, there are little things that seem “off” from an orderly perspective: the right side isn’t divided into two images like the left side, and the top line of text goes much farther over the center than the bottom line of text.
You can either try to “fix” the orderly layout or you can go the other way and make everything more dynamic and a bit chaotic. Given the subject matter, I recommend the latter. Put the text on a curve, or just rotate it a bit. If you need to split your image into multiple fields, divide along diagonal lines and don’t make the fields the same size.
