Great drawing as always, I love it!
With the lonley man in seemingly high-tech clothing walking all alone in a barren wasteland where the ground is barely or not at all touched by the light of a sun, you really get the feeling it's somewhere in outer space. Also, the clouds floating around make it look even more dangerous to live or walk there, maybe it's poisonous! Well, I doubt it would be oxygen, maybe it's lemonade! Just a random thought, but then the sky would have another colour..
Anyway, the overall picture, I adore it. There's the shadow I like, the landscape and the vague landscape in the distance make it more 3d.
The only con would be that his right leg, left for him, seems like it's a bit translucent, like blending in with the surface, but I shouldn't sweat on the details xD..

5 out of 5, definitely!
