Hi Bob. This is a beautiful image! The colors contrast dramatically with the black background and you have excellent DOF. There are a number of what look like cloning artifacts showing up in the background around the edges - these should be pretty easy to fix. Overall, this is very well done!
Bob, the black BG works incredibly well here and you have a very nice natural looking arrangement with wonderful colors. You definitely need to clone/paint away those artifacts and if this were mine, I'd also remove the lone bud in the LLC. What did you use as a BG?
