I think No 8 is transporting the idea of "Travelers" perfectly.
Like Masonspappy wrote the huge mountainrange and the tiny motorhome go together very well.
That`s a long journey they are on. Not just your average 2 week vacation.
This picture is telling a story about adventure, learning, dedication, companionship.
To me No 5 is not really up to the level quality of the 2nd series of pictures.
In comparison:
My impression is more a kind of being left behind, lonely. The sailing ship is leaving rather than arriving.
If I have it right thinking of renders you posted your talent seems to be right at home with these large
mountainranges spanning across the whole field of view. But who am I to judge

.
Which ever render you choose - Good luck!
