I do like your header as well, but I think your shop name is way too small. It should be more noticeable.
I also think your photos need to be recropped so that the the majority of the item is centered in the thumbnail.
You might also think about using backgrounds that are less patterned. Your little keychains are very cute, but they compete with the pattern on the fabric behind them, whereas your coin purses are easily visible.
The Rose ring, on the other hand has enough contrast that it looks very nice and coordinates with it's background without getting lost.
