I assume the problem is with my 3-D bucket from imagination. I started with the red line that runs through the center of the bucket, and then made a perpendicular line. Then I made the green line, which is supposed to be the horizontal angle of the bucket. the blue line is between the perpendicular and the green, that is supposedly the long axis of the cylinder in perspective. Is this the correct process? Can anyone help me with what I did wrong? Thank you so much!

Thank you in advance for any critiques and comments. I included a copy of my bucket stage in case that helps.
