Hi Congratulations on your first VCA! It's beautiful.
I would shorten it. The dangle makes it look like the bracelet is too big on you, which it is (it's like rolling up a pair of pants that are too long for you vs. really hemming them). The dangle also makes it seem like you are trying to make it look like a charm bracelet, but it's not a charm. You can see the end loop dangling so it looks sloppy and takes away from the elegance of the bracelet. That's my opinion, and of course everyone has their preferences. I would also get the 5 motif vs. Sweets. Sweets is really really reall tiny as the line was made for kids. Also, I think the classic Vintage size is more buildable for a collection and long term use.
The bracelet is beautiful; I would shorten it to keep it's beauty and elegance. Make it fit proper on you. For a 15 JUC, depending on how tight you like to wear bracelets, you may need to take out four links. Seeing how tight you are wearing it in the photo, I don't think two links is enough for what you want, so I think four links and maybe six. VCA has these sizer trial bracelets you can try on to choose your fit. Hope that helps. Congrats again!
