<human>: Can you give me the gist of the text in a nutshell?

We are in high school (I am 16, she is turning 16) and we've been dating for 16 months. Money is a bit limited for me since I don't have a job. I have managed to get $150 just for this purpose from mowing lawns over the summer (I definitely don't need to spend all of it, it could carry over to Christmas gifting as well). 
For her last birthday I got her a poster signed by her favorite band, and for last Christmas, I got her a print of art by one of her favorite artists (and I got him to write a personal message on the back).

She is an artist, and I'm a musician. We bonded over music when we first started dating, so those have been the basis of my previous gifts.

I've set a crazy high standard for my gifts, and I can't figure out what to give her this time around. I managed to get those for free by obsessively emailing people, but I haven't managed to make that work this time. I am intending to either buy a piece by her current favorite artist, but a few people have been telling me that I need to get her something more personal (jewelry, clothing, etc.) and I just don't know. 

Thanks!
<bot>: Would you (women) prefer a piece of art from your favorite artist, or something like jewelry or clothing as a birthday gift from your boyfriend.
