I think making the effect a little more abundant and to the point would be nice, also when doing a B&W tag , try to make the msot of the lack of color by adding some high contrast between the white and black , photoshop cs3 has a cool feature that will auto mate this for you, also if you dont have cs3 use and baslck and white gradient map insted of just desturating the images
overall its lakcing but i can see the potential to be great
