Ponderings From a Budding Author...Maybe

I have been in my fanfiction writing sandbox for three years now and am seriously considering trying my hand at some more serious writing...or a "real" story/novel of original fiction. So here's where all of you come in...I have a few questions that I need to consider or need your help to answer.

#1 Do you prefer reading novels written in first person or third person? (Most of what I have written has been in Third Person Subjective Multiple Viewpoint or Third Person Omniscient, but I have done some first person perspective)

#2 What types of stories do you prefer? Real life? Sci Fi? Mysteries? Drama? Suspense? Action? or what ever your preference might be.

#3 and please be truthful. If you prefer to post in private send me a PM, but I really want to know your opinion. If you have never read my work then please visit my website and take a look. They are all Emergency! fanfiction. There are short stories and long ones...even novel length ("The Boot" and "The Fire Talks"). Here is the link: http://www.adventurescomingtolifeinwords.com

And so the biggest question is: Do you think I can pull this off?

I'm not looking for "rave" reviews. I seriously want to know if any of my friends that have read my stories has an opinion on the quality and saleability of the work. Also, if any one out there has any suggestions, I am open to any help you might have to give...or if anyone knows of the steps to make something like this happen or who I might talk to...that would be great too!

THANKS!
