That 'park' looks nice in the renders, but in reality will be very challenged in terms of sun.
Block A appears to be large enough to support shifting the Metro into its ground floor.
IT would be worth considering, simply to finishing modelling out the completed project, but also to see one couldn't squeeze both a bit more park; and bit more sun for said park into a complete plan.
From the point of view of usable parkspace, it would be better if the Block B building were sited at the north end (where the parking is).
Parking for Metro could be retained, but shifted under either the Block A or B buildings.
