I expanded my beta reader pool by putting an invitation for beta readers on my Facebook page. Mary, on the Writing Excuses Podcast, said she has fans do her beta reads. Since the only fans I have so far are already readers, (that's like, four people) and mostly family members, I felt like I needed some new blood if I'm going to take my writing to a new level. I'll be over the moon if someday I have enough of a fan base that people I don't know, other than from getting feedback on books of mine they've read, are asking to do beta reads for me.
I got some feedback on my current project in beta from one of these new readers that really made my day. He said that he'd love to see this book as a movie because of one of the scenes he had just read would be classic. I don't want to tell you the scene, because you'd lose the full effect of it if you ever read the book.
Why I took this a such a compliment was that I had created a scene original enough and delivered it clearly enough that the reader was able to picture what I had imagined in my own mind and attempted to present with words.
Let me take a moment to pat myself on the back. (I'm fairly insecure about most things I do, so I need to boost my self confidence whenever I get the chance.)
