A street view screen grab with the sculpture model superimposed would have been far superior to that SU rendering.
I do think that that roundabout is a completely inappropriate place for a large sculpture. But the positioning of the model in SU is ridiculous. The barriers are extremely large and there is a wide distance between the barriers so the sculpture needs to go between the barriers, it can't be behind them as they are in the model.
I don't think they are particularly bad, they just look like really quick models to me. Definitely not suitable for publication, and they've only probably been published because they were free and the newspapers are churned out quickly and will accept any rubbish picture they can.
