Seems like a bit of a disconnect with the type on the page versus an ink pen. Why not write the words out instead of sticking a piece of paper on the notepad? The message is funny. Lighting is a little harsh (a softbox or light tent would help some with this).
i kinda share the feeling (esp. since i recently started to teach at a univesity here :-) and at first look i liked the composition and your choice of colors. but after second look i wander why the letters next to the pen are printed and not handwritten, why the line beneath them gets thin... it make is too artificial, not a remark someone would write in school when bored...
Expose on this is a bit uneven, but the big problem I have with it is logistical: "school sucks" is typewritten but there's a markere on the page. I think it would have worked better if you either had "school sucks" typewritten on a page coming out of a typewriter or printer or had it written in marker.
