There's a difference between a portfolio and a catalog. You may be trying to show as many photos as possible - as large as possible - to the detriment of each photo. That's more like a catalog than a portfolio.
Perhaps you could consider giving a more flattering border around each image: via either a larger book, or smaller images.
The two-up approach looks rather cluttered: similar photos compete, and dissimilar images interfere with one another.
Each photo deserves to be shown as a work in itself. Leave the left page blank: that's a suggestion anyhow
Better to show a few images with dignity and elegance, than many photos crowded together.
