Hi
MSUprep and welcome to the forum!
I hope that you don't mind, but I thought that your subject matter might be better suited in the "New Users" Area here, so I have moved it from the 'Showboard' board.
I'd also like to mention that the link that you have posted only directs me to a blank page. [confused]
With reference to your query about using a combination of
Illustrator and
Photoshop to create your Pen & Ink art, yes you can do it that way. But I'm wondering why you wouldn't use Photoshop's vector tools and save yourself the time and hassle of using 2 applications to create what one will do?
I've not seen tutorials "out there" that deal with these two separate techniques as one topic. Certainly there are lots of decent "pen tutorials" out there and plenty more "coloring" ones. A quick search with Google should find you both.
You mention that the pen tool is a bit of a mystery to you. I'm attaching a very basic tutorial that will help you to get acquainted with it. Hopefully, this will get you started.
