Jennifer, I'm not knocking it. I just prefer your street work, which is way out there beyond what most people are capable of doing on the street. If Tom's right, you might look for backpackers jumping off bridges.
But Mike and Pop are both right. The tone mapping could have been better, especially the sky over the hgher part of the hills. If you decide to go to Photoshop and can afford it, give a thought to adding Nik's plugins. Silver Efex Pro is the best B&W conversion software I've seen. In the color version of your picture, before you made the B&W transition, Viveza would have let you very easily correct the sky tones.
Instead of Photoshop you might think about Lightroom. For a photographer it has practically everything Photoshop has. I stick with Photoshop because I've used it for so many years that it's become an old friend, but if I were just getting into serious post-processing I'd probably go with Lightroom. The Nik plugins work with Lightroom too.
Hope your health problem goes away soon.
