First picture is a bit off;
Void is seen, left character is floating a bit, and the lightning looks bright on the middle character.
Second picture is very good though! I really like the reflections
They are not floating, the terrain has changed during the rendering (and I fixed it anyway). The Light is the glare of the sun reflecting off the metal armor. And star wars has an infinity of planets, many of which have real terrain. And the lightsaber has nothing to do with clones …
So, as I wrote above, during the rendering of the image, the modifier changed its properties, modifying a minimum the appearance of the terrain and thus making a kind of vacuum under the feet of the rig. (anyway I fixed it)
The second one looks amazing but for the first one poses are a but too stiff and lightining looks weird plus the background has things that do not really convince me. It’s overall very good.
