Okay can do the bikini shadows bit, but I dunno what all the rest of it means. Like whats tyo? In the evening it should be low to the horizon not above like you currently have. But... but... I thought it WAS low, (see screen grab) the first a slightly orangey/red sun from low in the sky. the second is a small blue-white fill for the opposite in azimuth from the sun and further up in the sky. Make this about 25% of the suns brightness. Dunno how to do any of that, sorry. Lastly I would introduce small bounce a what??? (say 10%) light fills coloured to represent the light of what they are simulating the reflection off of. Wha??? (bewildered expression) (you could add a caustic gel to the one for the light bounced off the water for example) Now that sounds quite nice, dunno how to do it or any of the rest of it... Help?
