It's more than 'not bad.' Nice tonal range and depth of field. Wonderful textures.
The composition is rather static, with the frame evenly divided.
You might try a more tilted angle. Diagonals lend a more dynamic feel to an image. Even distribution of shapes lends a more static feel. Neither is correct, but knowledge of this can enhance the 'feel' you're trying to achieve. That's why you'll seldom see a good image where a horizon is on the half line, bisecting the frame into equal parts.
In your image, the grill work bisects your image, and also evenly divides it into thirds because the grill work has height. The grill work appears to be your focal point, and off-setting the focal point up or down, or on a diagonal will often create a more dynamic image.
You've a creative eye. I'm looking forward to seeing more of your photos.
