I generally like the first two images, but I've been in a shooting mood of late looking for such images...lines, shapes and such in everyday life.
1- Great lines here, really interesting subject. I'm not liking the background water fountains, and I'm unsure about the red part on the bottom. While getting closer in would of helped minimized the distractions that are currently taking from the main subject, I think it might have been hard to achieve the same look with less in the image.
But be mindful of backgrounds...use a wider aperture or telephoto lens to make the background blurrier. How would this look cropped and in black and white? I feel that BW really draws attention to shapes and lines and helps hide things that are less important. Red is a really strong colour that draws the eye, but if you still want to show the red hitch but not have as much attention to it, try it in BW.
2- Great image, I really like this one. The thing I'm iffy about is actually the part that is in focus. There are some great shapes in the bokeh and lights, and i find this appealing to my eye, and the part in focus is a bit harder on the eye.
3- Uh, I dont like this. I find the selective colouring not very well done and I see grey blood spots and red blood spots. The image looks a bit soft as well. Selective colouring is a tool used to draw the viewers eye to something of importance in the image... I find the blood isn't the important part of the image, but its the statue.
