C&C Per req:
1. Neat image; I'd suggest levelling the black line from which the drops are hanging.
2. Nicely done, I like the technique, but feel the sun is just a bit strong.
3. Neat image; I would prefer to see it leveled and without the top of the umbrella cropped. The big concern I have however is the model; she really looks like she'd rather be anywhere but in front of the camera.
4. I'd suggest straightening the candle.
5. Another interesting idea, but too many small distractions. The chimmney, and satellite dish on the wall, and whatever object is just behind the umbrella that you can see the top of.
Just my $00.02 worth - your milage may vary.
