Take some time to get the album submission/image organization worked out before the 250 boxes as it's going to be a real pain if you do those one image at a time. I also recommend getting these in order for future submissions as it'll make it easier to provide feedback in the future to let you progress.
For the organic perspective you shouldn't feel bad about drawing through the shapes, and it looks like the vanishing points are going towards the viewer rather than away, make sure to pay attention to the orientation and direction of the vanishing point as you move into the 250 box exercise.
Your linework otherwise looks good and patient, keep up the clean look moving forward.
Next Steps:
Proceed to the 250 box challenge and pay special attention to the direction of the vanishing points when going through the instruction for guideline placement. There is some supplemental materials on the discord as well after you've had a chance to do a few for yourself.
