Nice blues in the upper part. I think getting the background to be WHITE would really make this pop. Suggest setting your white point for the color temperature of the light and using levels or curves to set the background to pure white.
Good choice of colors and lighting. Although, I think that this image should not have been taken on an angle because it is a distraction and takes away from the main focus of the image.
The saturation on teh blue is a bit overdone (you can notice it majorly on the glass stones at the base of the candle holder. This is an interesting angle, might have also went with a brighter border (to match the blue glass).
