What went well

Touched down at -175 ft/m — a soft arrival
Threshold crossed at 55 ft and 138 kt — both inside band
Straight touchdown — 1.64 m off the centreline, no bounce

What held you back

Arrival Landing — Flare profile at 0 %, −1.05 points
Arrival Rollout — Runway alignment max 15.78 m at 54 %, −0.87 points
Departure Roll — Liftoff speed was 181 kt at 80 %, Runway alignment max 6.41 m at 88 %, −0.43 points

Top opportunity

Work on the flare

Arrival Landing

Arrive slow and the sink rate at the threshold is already above schedule, the flare is short because there is no energy to extend it, and the touchdown is hard in a way that feels exactly like a late flare. Diagnosing a slow arrival as a late flare is the catastrophic misread: you respond by flaring earlier, which bleeds more speed, which makes the next one worse. The tiebreaker is threshold speed against VRef, not feel. Never diagnose a flare without it.
