Phalenopsis "Bachmans New Century.

This is a shot I tried for in my studio and am pretty happy with.

Any suggestions for improvement?

My only pick would the sharpness of the photo. A little sharper and this would really standout. Good work on the color.

Yes I'd sharpen it a little (although its pretty sharp already in my view). The other thing I'd do would be to remove the green sprig that goes nowhere and distracts from the petals. My only reservation however is that the black background being so very strong for isolation purposes creates the appearance of the orchid floating in a large black hole. So I think to reduce this effect I'd then crop to the point where I felt the flower didn't float but was supported by its stem.
