My personal view, is overall looking much better than previous screenshots had shown.
The internal flight deck views look fantastic.
The external views, whilst much improved still have a little way to go.
There is a lot to be positive about here, for example the engine mounting pylon correctly rises from the fuselage to the top of the inner engine pod. The tail looks far more accurate than earlier screenshots, as does the nose profile (although, still a little blunt) and the shape of the engine pods.
Still needing some work, are the inner wing fences. Too low and incorrectly shown wrapping around the leading edge of the wing.

Also, the main gear doors look too broad front to back -

Overall, the model looks very good indeed. The virtual cockpit looks incredible. The external model looks vastly improved over previous images.
The fairing on top of the tail, attaching the tail plane I feel needs to be more 'full bodied'.
The only other minor issue, is the landing/taxi lights set into the lower nose. These look quite large and elliptical, compared to the photo of the BOAC VC-10 shown above.
I'm no expert and have never attempted to build a flightsim model. I'm sure that the minor issues that I've highlighted will be addressed and the final release will be something I'll be happy to buy (as long as it's P3Dv4 compatible).
