To dark in some areas, and flat in others. The bricks dont have much of a texture, and you cant see enough of the lamp as it is lost in shaddow. More contrast would also help
I can see how you tried to balance this image, but the color and light really need more oomph, especially with such a simplistic subject. Could be sharper, too.
Interesting! The angles really work and I like how they are angles I might see in real life (rather than rotated for the sake of it). The crossing diagonals work well.
