Well it appears you are using two light sources. Consider the mountains in the background; the right side of them is heavily in shadow while the left side of them is well lit. This normally would be fine as single light source can do this from above and to the left, but then you also have the sun light "burning" (a light source that is so bright, it mutes all color on anything it is displayed on) the tops of the mountains like at sunset which would mean the light source has to be much lower and behind the mountains. However, the section of mountains on the right are missing any of this same "burn".

Meanwhile, the trolly or tram in the foreground has shiny points on the corners facing us, which means some light source is behind us.
My gut reaction is also that since the side of the trolly faced away from the mountains (NOT the side with the glass), is also faced away from the sun AND is behind a section of the broken bridge, that it should be fairly in shadow at least as much as the mountains to the right.
It isn't.
I don't know why.
I'm sorry, I don't know photoshop nor vray to be able to explain how to fix this...

This concept is very complete though, that you tried to show an entire environment instead of just one object which I applaud. Meaning it is very difficult to try to cover so many different elements and angles.

You might want to go with a more varied texture for the mountains, instead of making them all grass covered green, likewise for the blue of the trolly. That would give it a better realistic feel and less of a "showroom new" look about it. Again, not something I am that skilled with (as I am trying to work out how to achieve the same results) but maybe someone else can explain how to go about that...

I may be wrong but it seems your scale of the airplane is a little off? Being it is up in the air and thus further away than the housing "below" it, should mean it is smaller, but instead it looks (based on the scale of the houses below it) to have a wingspan of about 400 ft wide? (For example, the Boeing 777 has a wingspan of only 60 meters (197 ft))
(it should also be experiencing some "burn" like the mountaintops too but is instead, completely in shadow)

wow really explained the concepts of light, enough to consider thanks really appreciate it, and mountains could not get another type of texture but I'm looking at groups of textures to improve, the plane, I will consider all the information that you give me, really thanks

Good modeling and yes, too much of photoshop, there must be much more sharpness.

It looks really cool! But what is your focus on the picture? It seems like you want to show the environment but a lot of focus goes to the water! Just a thought
