Feeling unsure? I think you need to tell your closest friends and family your plan then tell them need honest truth, "Good enough for hobby?" or "Good enough to professional publish?" Next to always get second and third opinion from publishers because not everyone likes the same types af art, my art and my poems are very dark and some people find it depressing but others find them amazing. Some publisher will maybe known by book store for just your type of poetry so you need to try several places before you lose hope, don't let them tear you down! I do believe that your closest frinds and family is your best bet to begin if you think they will support you in your new venture, good luck!
Did some quick search for you, I found type in google "copyright registration" then go to Basics of copyright by About.com, and you can also go to website Writing-World.com for publishing basics and steps to take, hope that will get you started on your new road. I do realize your friends and family never criticize your work but important they tell EXACTLY their opinion about hobby or publish I don't know them but sure they can do that for you, I don't think they would embarass you because they love you! Your toughest critic is yourself and you need to beat the critic and believe in your ability! I have some art in my album if you like to stop by, luck luck luck...Later
