Working with what stays
Keep the stone lintels separate
The clay-colored example has pale stone sills and lintels around dark windows. Preserve those material changes in the comparison; treating them all as painted trim would answer a different question.
Consider the stoop and street view
A door accent is seen with the stair railing, paving and adjacent buildings. Compare from the full street-facing image before focusing on a close-up of the door.
