What I'm noticing on the ellipse is they arent touching both the top and the bottom. As you're coming around for the second pass try to see if you can touch both. On the boxes it looks like on some you arent quite sure where to place your line. Uncomfortable has a good video on how to draw a box using thr "Y" method that helped me alot. Remeber to try to keep them parallel with the lines slowly converging to the "VP" they're sharing. I think the rough perspective looks good. The funnels are good. I'm just new also so I wish I could give more advice but thats what I see. Keep up the good work!
