Definitely "Lonely Enemy" - Shows what the game's about.

concept rocks!

Wow, near unanimous.

Honestly, "Lonely..." is better as a concept, but the second pic is better by quality. And I vote for yours because I support good concepts.

The second one, without a doubt.

Chess 1 is a good concept I like the way the chesspieces are standing from less important towards the king.
I also like the piramidlike shape ezoog got there.
The mirror is the finnishing touch.
I like it really much.

Yet Lonely Enemy is better by concept.
The depth of field just drew my attention and the way the picture is took is is just pulling my interest.
I think I'll choose for Taenaron.

Lonely enemy wins this round

I'm a perfectionist, so anything that is out of focus and a potential distraction drives me crazy!

"Lonely Enemy " is by far the better type,
shots like this are more intimate and
comfortable ......

Yours is funnier, cause one against all

Great Work
