I do the same kind of shooting so it was great to see your shots. Can't wait until spring and summer to put the cam and lenses thorugh their paces..especially now that I've sold my D7000. The Poinsettia is a great teaching shot...so many think the bracts are flowers and you clearly show the flower and the bracts in perfect and clear contrast.
