The bridge

Night time..................

A nice lighting impact. Maybe just a teeny bit of side light to reveal more of the bridge detail?

I do have some hints again: the ivy is quite large, too large, so you might want to redo that. The water is perfect but I miss a wet edge on the object. You can add a reflective shader as child to a surface shader masked by distribution shader inside the object, just figure out the water height and up it 10cm.
And I'd add some extra world space PF displacement on the bridge, especially the underside, it looks like it only uses a too soft image map.
But this has a lot of potential.

Made some changes...............

Very good improvement lighting up the bridge. Maybe ivy could be smaller?

[yossam]

Unfortunately they are part of the mesh...............not much I can do with them.

The ivy doesn't bother me.  What's poking me is the bump mapping under the bridge.  It looks very low resolution, scale seems too big and the bridge itself looks like its floating on the river as the water's illumination is constant across the whole expanse. 

I'm not sure how that last issue can be addressed as I don't believe TG renders water as a real volume that can have shadows casting through it but if it can you could try adding additional geo that extends down below the water level where the bridge touches the water plane and see if that fixes it.

Fully agree with gregtee. The texture on the underside just sticks out. Does the bridge model have a foundation? If so, water transparency settings may address this. Otherwise, you may have to sculpt something to support the bridge. I like the composition and light. This could be a great image if you keep at it.

One mo' time....................

Except for the ivy leaves, all looks as the best improvement.

Last one is very nice. Great improvement
