Hi, the section is explained very well. However, I struggle with the last assigment. How do I fulfill "they should have different vanishing points but feel as if they have the same horizon line". I wouldn't even know how to do that for boxes. I think I am missing the point how to introduce more than one pair of vanishing points if you have to depict multiple objects (boxes, cylinders etc.) that it still feels like they are in the same "room or place".
I'm a beginner so take my opinions with great filter :) If your goal was to be 100% accurate then for me it seems that you're bit off. If not, looks close enough to work. My main "problem" is that you're using grids that give a lot of distortion. Again it's not bad if you planned to. If not planned, check out some article(s) about POV in perspective to have more realistic look :)
Hello Marco! Glad to hear about your AMA! Got a simple question - if you would have to choose 1 or few exercises to do every day that are most important for improvement (as far as generalization of all artists worldwide go) what would they be? If possible, split for beginners and advanced. Love your work and courses, hope to see even more!
