Hello,
This is my current (long time) ongoing project. Wanted to create a quiet roadside with a big tree and some small shop nearby at sunset. My concern here is reg. the lighting, the current result for me looks good for a sunset, but I get the feeling that the scene is too dark. But if I increase the sun/HDRI power it looses the sunset feel. May be my monitor is not well calibrated.
Any suggestions or feedback are welcome to improve the realism w.r.t to lighting.
I know I need to improve some modelling and textures 
.
Thanks!
