First one is not bad. The subject is good, but something tells me the composition or framing isn't quite right. I bet it would actually be neater if you only saw ONE of the brick walls and the other was cropped out... possibly get more play off the reflection of the wall on the glass at the same time.
The third one with the lamp is REALLY nice. I love the colors and the softness of the light... just really really nice. Framing is great, too. Very impressed with it.
The last one is kinda neat, but didn't totally work for me. Positioning in the frame, perhaps... not certain.
BTW looks like you have dust on your sensor. Look on the right hand portion of that shot and you'll notice a small darkish dot.
