You have some great skills with drawing in Illustrator / PS, but may I saw that was not really a pen tool tutorial.
Such as, when you said just draw the dart board / poster on the wall, there was no step by step on which tool to use, whether or not to use a drop shadow, how to change the perspective of it, and so on.
If you are making a tutorial for the pen tool, you may also want to include the path lines with where the anchors are etc.
