The ambient (natural or artificial) used in your photos is too flat, not enhancing the three dimensionality (3-D) of the flowers. Most "flower photographers" use speedlights to increase DOF,and define dimensionality of flowers.
Here is what a hand-held standard DSLR with a macro lens & simple 3/4-circle (partial ring light) can do for orchids.
I can tell you've got the experience! I didn't have a ring light, the flash I had was not what I needed, and the light in the room was much brighter than I'm used to seeing it, so I think it's a process problem. I will have to spend some time doing shots here at home and see if I can work out a system with the equipment I have.
Thanks for sharing - I'll compare mine to your technical level until I get better! It's always good to have some stunning shots to aspire to :)
