This was a super idea for the challenge. The little cups and saucers are precious. The color on the background seems to be a little off, the focus seems a little soft, and there seems to be a lot of noise or graininess. I hope these observations will be helpful. :)
Good subject but I think it could have been arranged and captured better. Maybe a red background instead of the white. A bit sharper focus and less grain.This is just my opinion. It may be the your choices here were designed to give this an old world look and it certainly achieves that.
