First: I love the poster. Just want that one initial point clear.
Next: the angle of the scotch tape (+/- 7 o'clock position) is weird; especially when all the other art tools seem to have the same perspective from my own eye. I understand that the scotch tape's angle is intended to show details, but it still looks out of place. At least from my eye.
Aside from that one small detail, I must say that everything else is perfect.
(but then again I'm not an art student, and I have been known to have perspective problems with my drawings)
