"San Francisco" has potential, but if you can, you should definitely turn down the ISO on your camera, because even though that makes it need less time to expose, it makes photos turn out really grainy.
I very much like "Untitled" (one of the lighthouse thing), but I feel like you've positioned the lighthouse too far to the left of the frame...the space between the lighthouse and the left edge just seems uncomfortably thin. That is my only issue with that photo, the subject, angle, and lighting is all perfect.
One of my favorites is "Hood Droplets", it has a real nice modern feel to it. It's simple, and does the job.
The last photo on the first page, the black and white one of the bridge, is really cool. What would make it even cooler if you could widen your perspective so that the reflection of the bridge was also fully in the frame. Only a suggestion, but it's something I would have done.
As for the second page, I REALLY like "Marina". The red light and the reflection on the water is key. Again with the night shots, turning down the ISO is pretty much necessary, but not as noticeable here.
You've got a handful of real nice shots, and then a good amount of shots that could be real nice shots if a few small things were changed.
