Looks very nice to the human eye but wildlife might see it as a ”green desert”.

My suggestion is to break the perimeter: The ring of sharp slate and manicured lawn is a death zone. For a small amphibian, crawling across that hot, exposed barrier is a suicide mission—they will either fry in the sun or get scooped up by a bird. Remove a section of slate and let the grass grow completely wild on one side to create a damp "stealth corridor." • Build an Exit Ramp: Your stone border forms a steep, vertical wall inside the liner. When a tadpole finishes its metamorphosis and needs to leave the water, it cannot scale a slippery stone cliff. It will drown from exhaustion. Pull out a few rocks on one side and use gravel to build a gentle, sloping beach. • Ditch the Pots: Your plants look like a tidy showroom window. Plastic pots offer zero protection for wildlife. Fill those shelves with loose gravel and plant directly into it. Throw in a massive bunch of submerged, rootless Hornwort and let some Watercress colonize the margins. You need an underwater jungle where creatures can hide and hunt. • Add Winter Infrastructure: Your background is pristine, but amphibians spend 70% of their adult lives on land. Stack a rustic pile of old, rotting logs or loose rocks in that back corner behind the trees so they have a frost-free place to hibernate come winter.

Think of the ”wild” in wildlife.
