It might be because I am old and therefore maybe also old-fashioned, but I best like the straightforward photos here, such as the first, second and fourth.
The first includes all of the boat, nothing is cropped, which I appreciate.
The second is interesting because it's got leading lines, lines as such, repetition, and a person to add some "action" and "life" to what would otherwise have been utterly boring (despite the elements I named and like).
The night photo might be considered a bit dark in places, but the aperture was nicely small (star effect of street lights and no big bright blobs), the small houses and illuminated street in the foreground offer a pleasant leading line towards the highrises of downtown, well, and those form a nice skyline!
Skating photos don't talk to me (age, I guess) and the last ... makes me wonder. I would think it is a long exposure, and you changed places while the camera was exposing, but knocked against the table in the process?
By the way, this last one may just be one of the exceptions to my "rule" ... I actually quite like the selective colouring in this one
