#20 of 29 Faces and art journal

I have been wanting to start an art journal for awhile now, but really didn't know how to get started, I was doing a little cleaning the other day and came across a blank scrap book that I had bought at Barns& Nobles about 10 years ago for a dollar. I don't scrapbook but couldn't pass it up. Well I found a my answer for the book. Here is what I did for my first page and I really enjoyed doing it. And I have one question maybe someone can answer for me. When doing  an art journal, do you put a finish on the page like varnish? I am not sure I should put it on or just leave it.
