Feedback to my tutorial - Please

Hey everyone,
I hope you are doing fine. On sunday I finished my first tutorial but until now nobody opt in or gave me any feedback. I would like to know if you can give me a short feedback...? I have been thinking about posting a job on elance to obtain some feedbacks but I believe that is way too expensive... Do you know a page where I can receive feedbacks for free or by giving away my whole course.
Please let me know
best regards
Reggy
