Arid scene with humanoid figure

Hallo everyone (English is not my mother tongue. Corrections are very welcomed)
This is some work i´m doing for an installation project for my art´s university.
This will be part of one of the three scenes that will be played in three TVs putted together, forming one whole scene.

  • Which do you like the most?

  • Does someone know how to avoid the pixelation that appears in the floor texture even tough it is very big and high res?

Thanks

I would lean towards either 1 or 5 but the lighter grounds tend to give more of a hot desert feel.

The colours used in the other 2 pics might influence which one fits in better.
