I finished the draft of my first chapter today, and tallied another 2500 words leaving me at 5189 words total. So far I'm liking my plot and loving writing setting descriptions, and bringing my secondary characters to life. The biggest problem that I see is that my main character, Lena, seems a little bit bland to me. It's funny because I am writing in first person, so I thought that her personality would come through strongly, but instead the other characters do, because I'm writing about what Lena is seeing, and she doesn't see herself.
Anyone ever had this problem before? For you more experienced writers and NaNo-ers, do any of you have any tips for making your main characters believable and intriguing?
Thanks!
