Place the fungus on image 1 on a left third of the picture and the first row works. Image 4 and 6 do not work well together as book ends: the subjects, composition and tones are too dissimilar.  In row 3, image 7 the field mouse should be placed on the left third to improve the composition to make it an effective bookend. Image 8 is too urban and different from the rest of the panel and the hare, image 9, is too big compared to the vole and thus dominates the row.
