Nice portrait ! The angle is a really good choice, it makes the picture stronger than a regular angle. Your brother seems a bit unhappy with you taking pictures of him ! It's a shame if he actually is, because he is very photogenic !
However, I don't really see the point of leaving the ground in color. I think that the b&w was a good choice. And I like that the ground is in color... but I just don't get why you left it ! I'm curious ^^
