The lighting seems to be weak to be honest. It looks like it has lens flares which should indicate that there is strong lighting but there isn't
Like it, but I'd would like to see a lightning bolt some where. Gives it a better concept of the title dead man walking.
he doesnt look dead maybe add some blood or like santa said, lighting. The colors and text are weeeeeek. the lens flare seems really awkward because there is like no light source. the background just screams filter>render>clouds
Yeah I don't like the clouds nor the text and lens flares but besides that, it has a great concept and you did pretty good with portraying it. Just fix the flares and the clouds and the text.
