There are quite a few, but I'll point out two aside from the fact of multiple double texts.
The first one is the message where you included "sorry" at the end. This gave her a hint that you're not confident in what you say even though you trying to be playful or pass it off as a joke. The message would've been great without that word.

Second mistake was where you mentioned that you took her bio seriously. Even though you may be thinking that, don't ever tell that to a woman because once again it gives her a hint that you think too deep into certain things, and an in-person conversation wouldn't be as entertaining.
