Wow, i love the first one it's got some great patterns. What exactly is it? kinda looks like the overhead wires for a rail line but i've never seen them with lights on it before.
Number two is really cool too but i think it could have used a bit more light on the teapot just to define it's shape a little more clearly. However, i'm afraid it might have washed out the flames on the burners. Still a really good shot.
Number 3 is wild, the shadows are tricky. I can't really tell if or how much the door is recessed into that wall or not. Similarly at first glance it almost looks like the narrow striped in the wall are the high spots and the wide flat parts are pushed back (untill you get to the corner).
