So that’s your debut? My congratulations! Wish you great career in writing (and coding, of course). I agree that you indeed might have a style not to my liking and there are more people who like it, so the following is only my personal subjective view.
First, I would recommend reading The Shallows if you haven’t read yet, just to know your intended audience better.
Second, I doubt a lot of readers are interested in your experience of being blond and insecure about it (well, may be two or three sentence, but definitely not THAT amount of text). And in the end the you compare two incomparable things: things you want and don’t want to sell. Your coding skills are what you market, and your look is not, right? So why compare?
