So it's not surprising that this tank checks most of the boxes - right number of species restraint with red plants use of large-leaved plants a plant street the disappears behind another bush the use of curtain plants appropriate contrast.
Yet the tank feels somewhat off-target. Why?
The focal point (Echinodorus) is too close to the center. It would have been better if placed a little to the right. Street placement in the center divides the tank. Many of the plants are very recently trimmed giving the tank an immature and unsettled appearance. The back left corner is very dark. While it is fine to see the back wall there is simply too much back wall here.
PRO-TIP: there is a rarely discussed part of Dutch scaping that I call 'Days-to-Peak.' Understanding this and applying this knowledge would have greatly improved the ranking on this entry.
Days-to-Peak (DTP) is the number of days it takes for a species to grow to perfect height and volume after a trim. DTP is different for every species and every tank. Given your light CO2 and fertilizer dosing Ludwigia inclinata Pantanal may take only 5 days after a trim to reach peak appearance of perfect height and volume. Whereas Rotala may require 10 days. Knowing the number of days it takes for each of your species to reach its peak or best appearance after a trim is critical. Knowing this tells you when to trim each plant so they all reach the perfect height and volume when you are ready to photograph the tank for competition. Maintaining the same species for a few months without changing light ferts and CO2 and observing them daily while keeping excellent records will help you determine the DTP for every species. Experimenting with dosing or CO2 while getting ready for a competition means your DTP will keep changing. Without knowing DTPs for each plant entries will look too freshly trimmed or overgrown.
