My favorite would be #3.
With that, I think that both 1 and 3 need a little bit of highlight control. Most of the steps in #3 are completely blown out, and the center of the building in #1 is also blown out.
I'm assuming that #2 was a long exposure shot. Your depth of field is quite large. I just think that maybe a bit more sharpening to bring out the details. But it's looking nice. May I ask what time that was taken? That spot looks to be perfect for night time long exposures. Like when the sun is setting/set.
The first macro shot is pretty nice. You've controlled the light very well, and everything in the image works.
The second still life shot is very eye-catching as well. I love the curl and color saturation in that one. The black background also works really well on that.
The fire pit/grill-looking, last image, is pretty nice too. Although, it's a bit different than the rest, it's a bit more vibrant abstract
