Looks very good. Shadows are looking very naturally. YOU ARE DOING A GOOD JOB, MAN. I felt them like as photo. Reduce a bit of chromatic aberration and add more sharpness slightly. Not on whole image, just edges. Better way to do it is on a copied layer with mask. Try to play with layers with various colour temperature / tint and mix these parts of picture to achieve slight transition between temperatures.
