URBAN STAR TRAILS!

I just attempted to shot my life's first star trails. I captured 70 images and then sorted them by star trails software. I shot from my balcony and the final image is satisfactory! This was shot from my home's balcony. I gave 17.5 minutes exposure (70 images with 15 sec exposure on each) to create this final image. All images are sorted with Startrails software.
