What about these ones for the Pages toolbar?

In order:

The new Hand Tool icon (I may make it a little smaller)

Add New Page before the current one
Delete current page
Add New Page after the current one
Add New Page at the end of the document
Go to Previous Page
Go to Next Page

The second attachment is for the Pen Thickness. Self explanatory.
The third attachment is the Colors toolbar.

Feedback on these ones?
