Here are some of my landscapes or cityscapes of San Francisco shot on a 5DIII and a 24-70mm f/2.8L. Hope you enjoy! Thanks!
EDIT: Thank you for the criticisms! Highly appreciated.

Hi BTN, I notice this is only your 4th or 5th Post, so not only were you brave to Post Images, but even braver to ask this Forum for Criticism, and as you have found out, the majority of people that involve themselves in the Forum, are dedicated Photographers of varying levels and only too willing to offer advise in any amount of ways to help other Photographers in a Positive way.
Some, like Neuro are not only accomplished Photographers, but exceptionally technical, Chaps like Gary Samples, rpt, Bdunbar79, serendipity etc etc, are a little of both, privatebydesign knows a huge amount about about Flash Photography, I've learnt heaps from these Guys on this forum, but.
You also have the Michele's and Dilberts, it's an open forum so you cant keep them out, if nothing else they do have humour value, albeit you need to develop a thick skin and learn to ignore the negativity of the down and outs of the world, they are generally born this way, so we need some compassion, and an occasional very large stick doesn't hurt, well I guess it does actually.
Onto the Photos, I love this City, one of my favourites after Florence, you've done an excellent job of exhibiting the City in your Photos, and like all Photographers, you have room to move your skill levels upward, I hope being involved with this Forum allows that to happen. I think well done & welcome to CR.
