I attempted to reduce the apparent thickness of the parchment, but doing so by simply reducing the width of the bevel or removing it entirely made it look crappy at lower resolutions. So instead I increased the brightness of the shadow half of the bevel, and I think that helped a bit, without affecting the appearance for low res screenshots.
I also adusted the color of the plaque a bit, and increased the bevel size on the screws while reducing the interior shadow on them to make them appear a bit larger.
I fixed up the window buttons a bit to make them less noticable.
Finally, I made the middle shades of the pencil a bit darker. Also added texture to the pencil tip and made it a bit darker. And added specularity to the lead, band, and eraser.
