I think the plan is very exciting and has many really good points particularly the aim to make the area more pedestrian and cycle friendly by removing the gyratory system, the new pedestrian link routes and an aim to green up have an amenity space.
It is important that the remaining pavements are suitably wide.

Moving to an integrated scheme seems ambitious and it may be difficult to persuade everyone of the benefits and there is a genuine concern about how it can be used by people with sight problems or poor mobility.
Maybe a mixed scheme would be possible with one or two crossings.
I couldn't see from the system whether the junctions would be mini roundabouts or T junctions.

The opportunity area should include the space( currently dotted line ) down to the river and wichcote now that it has been sold.

I think care needs to be taken with the outdoor amenity space 1 to avoid an unused concrete area as it is right by two roads and there aren't any obvious cafes near by. It is vital to use trees as much as possible to green it up.

The access road behind the tall buildings in the middle of the area doesn't need to extend further than Springfield road and the space behind could also be amenity space or under tree parking as there isn't any provision for parking which local businesses would value.
