Is it normal to gift some portraits to the girl you love?

So there is this girl that I met long time ago. We saw each other almost every single day, we were very good friends, and the more I got to know her, the more I fell in love with her. But still I wasn't confident enough to tell her about my feelings (I have never done it before with any other girl, it would've been the first time), despite the fact that this was authentic love, not just some random crush. Then I had this idea to give her a portrait of her beautiful face, aiming to show her my feelings in a way I could handle it (I'm pretty good at drawing and I really like to). I draw her picture and gave it to her as a gift, along with some chocolates, hoping to get the message as clearest as possible. But apparently it didn't work, she didn't see it in a romantic way, so in the course of the next year I kept making portraits of her, and giving them to her of course. In total I think I made like 4 portraits, some of them with a note trying to emphasize the way I felt. Nevertheless, things never happened, our ways separated and now that I'll probably never see her again, I wonder if I did the right thing or if I was too much of a creep. Until this day I think she is the most beautiful person I'll ever met. I just don't know if it was the appropriate way of showing such a powerful feeling.

TL;DR: I fell in love with a girl. We saw each other every day, we were friends, but I couldn't tell her about my love. So I gave her several drawings of her pretty face as a gift, to show her how I felt. In various occasions.
