Thanks Genevieve
thanks so much for your detailed feedback, I benefitted a lot of it, am using physical camera and lights I have main sun and HDR on the dome as well they work together for straight sun light and overall HDR light, I had to turn off the gamma on the HDR by the vray extra attributes, and render without affecting colors but affect background. Also i will apply vraySSS on the model skin. Image 3 is vray spherical panorama and I will introduce full panorama of the whole scene on my page, please keep following me. I will also join simply Maya shortly on a monthly basis, I believe it will solidify my skills.
Essam.
