This image has a sort of fairytale feel about it. The colours work really well. I would have opened up the depth of field so that everything was in focus. I would also suggest that cropping it to include the whole hot chocolate bottle would help to balance the composition. I think the foreground elements work really well. You've achieved a "random balance" in the placement and colouring of these elements.
The little bit of blur at the bottom is distracting, but other than that cute idea for a pic...like the white background because it makes sure that everything else stands out.
You need to bring all the elements of the image into the frame and into focus. Deepen your DOF and widen the shot to capture the top edge of the purple jar.
