I am really in love with the idea behind this photo and would love to know how you achieved the glittery effect! It suits the title of the piece and you can see what you were trying to achieve. I don't know how I would critique your make up skills as you're much better than me, but I can give some pointers as to how to make the photo a bit sharper.
Bear in mind, I started this critique before investigating how long you've been taking photos, or what your other shots are like, so bear with me! The lighting is really nice, I wouldn't change that about this piece. I'm not too sure if your Coolpix has many manual settings, but you can play with them a bit to make the photo less blurry. If it was quite dark, try putting the camera on a tripod and sitting really still. Also experiment with how close you can get to objects before the camera has an issue with focusing on the image, none of this picture is quite in focus. If you can change any of the settings manually, try a faster shutter speed. It will reduce the amount of shaking and make your image a little bit sharper!
I'm sorry if this seems a bit patronising, but I thought I'd comment on what I'd do to improve the shot!
