Lovely picture you've made here! :3 I really love the whole "amethyst" theme. The stones inside the bottle are a really nice touch- usually with little bottle pictures you see sprinkles or sparkles, but not too many stones. So that was a great change from the usual.
You also did a good job with the lighting; the corner of the picture gets dark, as if there is a light shining on the bottle. That really blends the picture with your title, in my opinion.
One thing that could enhance this picture would be a more creative point of view. The picture is kind of an an angle, as if it's slanted downhill. Maybe looking down upon the bottle would add a more interesting POV. There are endless possibilities here, and I would just encourage you to experiment a little. ^^
The clarity is really nice and adds to the quality of the image. The tones are cohesive and create a good atmosphere for the image, almost dream-like with the purples. The only big concern I have is the left side of the bow. It leads out of the frame, taking you away from the image. It also takes away from the image feeling well centered and detracts from the impact. The line cutting across in the back is also a bit distracting, but it does match up with the neck of the bottle. Taking into consideration that line, there are three areas: the white, grey, and the texture. When looking at all three areas, it does frame the bottle nicely after careful observation.
The use of the crinkled material is an interesting addition and adds to the whimsical effect. At first the light seemed distracting but it almost looks as if the material is glowing beneath which is interesting to consider. Overall, maybe more attention to composition in camera and placement of the subject would benefit future images like this. A well-lit white paper background is also a good choice for photographing objects with strong color like this.
