I think you've captured some nice moments in your shots, particularly the kid shots. Although, the composition of the pictures doesn't strike me as a strong point. You could argue that with certain subject matter, it's more important to capture the emotion (like with children) but you also need to be thinking about creating powerful composition. Although I like the shots, the composition is a little too weak, and fails to make my eyes 'read' the image.
I think your strength in his series is definitely your technical skill. You demonstrate the ability to achieve good quality pics, despite shooting in somewhat difficult situations.
As a side note, the spot colour of the eyes in BW Eyes looks a little over done. This is totally down to individual preference, but personally, i would reduce the saturation a little more, so that the effect doesn't look as obvious.
Hope all that helps!
