I just wanted you to see how fast Eevee was compared to Cycles when I told you to switch rendder engines to try it out XD I may have forgotten to tell you that you will need to mess with the lights to make it look nice x_x Yes you need to do a bit of tweaking to get something this good :)
A 4K rendering took approx. 45 sec. per image on my machine (8-core i9-9900k CPU, 64GB RAM, GeForce RTX 2080Ti). It took so long because of the recalculation of the high-detailed displacement modifier which was fed by a video texture. With a static displacement texture it would render in near real time. It took approx. 7 hours on the Sheepit renderfarm. On my machine it would take around 5-6 days.
