I dont see any actual translucent sprites. All i see is sprites with 1bit alpha.
Set them to masked and it already should decrease the overdraw.
Additionally you’ll either need to cutout your sprites, or enable “Mask Materials only in early z pass” in the rendering settings. It does wonders with masked materials.
If you want to stick to translucent sprites, (which I recommend it not doing) you should consider making them unlit/ or only vertex shaded
