5 - Nice concept. Like the subtlety in colors and the use of paper with the texture. A more finely tuned crop at the top, removing the green leaves entirely, make this even better in my opinion. Also, whilst difficult with the whites, a tweaking of colors to get them just a little 'stronger', also help this for this Challenge.
I love the focus on the front flower and the dof in the shot...only minor criticism is the pink cloth (?)...it could also do with a bit of a lift with levels in photoshop
