Well now this is some very interesting artwork. What's the style used? I feel like I've seen similar types of work but I don't recall what it is.
Also, what's the story here? The lone guy walking around in an area that seems overgrown and the metal looks aged and rusty in coloration. Is the world dead?
Side Trip, is this concept art for a series or a game? It reminds me a bit of some later PlayStation era games with the detail given to the background and the overhead view.
What's that red thing on the guy's head? At first I thought it was an icon but I see up close that was incorrect.
