First Car visualisation attempt in UE

FV_3D

I had three and half days to put together the assets for this scene, the car is from Turbosquid and I had to optimise and UV unwrap it in Maya, textured in SP and all the magic in UE 4.24. First time visualising a car . Any feedback will be very appreciated. I had issues with the reflections and the flickering of the light. Any brutal opinion will be very well received. also I would to ask for the experienced people out there if I was too slow. Thanks
