Hey, cute concept

The detail is a bit hard to find with a white background, which washes out your colours, green especially. The green doesn't really have much contrast between tones (Difference in hue, saturation and value) and so it's difficult to see the shape of the leaves!
Since green and red are complimentaries, they go well together in real life. unfortunately in pixel when you have small clusters of each right next to each other things can look muddled (e.g, can't really see the berries at 1x zoom) in fact, 1-pixel dots by themselves do what pixel art is generally about hiding - the true low resolution. With the colours, I believe that the reds could be more desaturated, or you have that problem with white, green and red fighting for dominance. There are a lot of one-off colours in the greens btw, probably got missed during recolour or something

If you employ hue shifting (in this example going further towards yellow-greens for the highlights and blue-greens for shadows) in the wreath and show bigger leaves (Remember: you dont need to fit everysingletinydetail into your pic

) The fact of what it is becomes much more recognisable.
I've made an edit to show what I meant & what in
my opinion could be improved (Shown at double resolution incase your browser makes fuzzies):

I changed the shape of the bow too- I think you may have gotten confused with the shape of a bowtie?
