Looks okay. But I'm sure there are some tiny issues that can only be fixed with a survey, because we can't spot them.

As a general point, I left these notes when passing by and seeing that there were a mess of footways that I could only get mapped may be 80% from aerial (and I was busy aligning and correcting all the major roads). So these would need a survey for the ambiguous and obstructed cases. Or just to confirm that aerial didn't miss anything.

My experience mapping from aerial in these courtyards is that I always miss a footway or two that I then only discover if and when passing through and paying close attention to the map.
