Great job on perspective - something I really struggle with. I love the different textures you’ve got as well. Only thing I can see that would improve the drawing are the buildings in the background - they seem to be just a tad out of whack with the bridge.
I think the drawing was using a super wide angle/near fisheye lens reference which makes the verticals tilt outward on either side, it is difficult to reproduce that distortion or correct/convert to rectilinear without a Lightroom or Photoshop lens correction step.
