Heres my CC, take everything with a grain of salt, Im still a beginner,
1. The photo right now is not very interesting. I agree with previous comments about maybe trying to zoom in or crop that one guy, perhaps making it more interesting.
2. Not very interesting at all, no clear subject, and it looks very crooked to me, try to keep your lines straight when taking pictures unless your going for an effect, (I don't think you are here). Sorry this one really doesn't do it for me.
3. Again not a very interesting photo in my opinion. THis one has a clearer subject but its still boring, sorry.
4. The street looks crooked in this again... Also again no clear subject. When doing street photography really try to zoom in on one main subject or else the picture will (most likely) just be cluttered and confusing. Sorry again if Im sounding tough, Whenever I CC I give me honest opinion, I don't like when people sugar coat when they give me CC so I wouldn't want to do anything to someone that I wouldn't want done to me on my thread.
5. This one definitely has a clear subject so its better, but the background is boring in my opinion, still better than the previous ones though.
8. I agree that this one had potential. I would have tried to zoom in more on the three people, but then again I have no idea how that would come out, just a option to try.
Keep at it. But next time I would highly suggest not taking photos from a car. It is very hard to get really great though out photos from a car. Walk around the city and really think about each photo, compositionally wise a technical wise before taking each photo. I know your new so don't take offense if you know already, but have you read your cameras manuel and do you know about all the settings and what they do? I can't tell from these shots. But if you don't know you shudl learn. Good luckl.
