Very nice model from the outside with a good amount of interior detail in the cockpit and a little less so in the galley and main cabin (the only major interior detail I missed was the lavatories; AFAIK the G650 usually has one in the front of the plane for the crew and one in the tail section for the passengers. This model has neither.) Some areas of the model are also suitable for close-up renders in terms of detail, but for certain meshes, a bit more smoothing of the meshes or the meshes being ready for subdivision/tessellation would have been useful. Since I use Cinema 4D with Redshift, I imported the FBX file version and converted it for Redshift: no major issues, but I found it a little difficult to match the look of the preview renders (not the fault of the model's creators, though). The main textures for the plane's body are 16K which I found a (welcome) surprise when I discovered that the project and texture files date from 2018 (I don't think too many modelers used 16K textures in 2018). Some of the other textures could be a little higher in resolution and normal maps would be nice. Overall, the model is a solid recommendation at the list price and a steal when discounted.
