By far my favourite piece in your gallery - I love what you've done with different sources to create this final piece.
As I mentioned before you have a very gritty feel to your work - I love it. I'm reminded of another artist on DA who you might be interested in: ~subzosa
The textures here really create a harsh atmosphere, and heighten the size difference between the ball and the figure. I'm really drawn to the layered feel of the sky - really nice how you've blended those straight edges together.
