you could add color to the leaves,, a thin wash of acrylic,, several coats till you get it righ(glazing),, then seal it,,
the leaves add a nice texture,, try on a scrap piece of wood,, I think you can make it work,,, with a little experimenting,,
maybe even some ink from hobby lobby,,, dilute the red and apply to the leaves,, add a bit of green if you need to dull it,,
if I have time I will try some leaves on a piece of wood to see if I can make the color work,,
