lol...you said shots from a couple of walks. I read that as couple of shots from a walk.
Lots of imagery there.
Many of them seem dark, either under exposed or having lots of shadows. Where many done over lunch time?
Some are neat images such as the banisters / railing in the first few and the glass building with reflection which I feel need a bit more composition work to make them pop.
Some are great, such as the orange coloured wall and sunsets.
If you want more detailed critique, I'd suggest posting 3-4 of them and number them so people can easily reference them.
