No. 3 and No. 6 are the best, IMHO. 3: the dog, peoples, and wall make nice composition. Funny and cute.
No. 6, narrow macro view and composition of ants to letters very interesting. Nice stock shots both.
Color images and BW nature shots are a bit busy and uncertain; what are you trying to actually express? Are you just looking for "good shots" or, are you trying to express something? As in, a feeling, a special moment; I need to know (without you writing it out) WHY you are taking these images. Why should I care about them? Why are they important? Or are they only wistful snapshots? Tough questions, but important ones. And believe me most of the time I do not reach the pinnacle either... 🙂
