|Greetings from the Critique Club!
Initial impression: Saw and it and thought, 'Oh yeah, it's an orchid'! Very distinctive flowers. Very easy on the eye, no glaring flaws.
Technical: Composition is straightforward, used ambient lighting. I do like the way the white petals frame the inner part of the orchid. Would like a little more dof; I don't really see any blur but some petals are oof.
Artistic: Again, a very pretty shot, but also a very safe shot in terms of how you shot. You maximized the symmetery of the flower's parts to help with the comp. A little more saturation may help.
Overall: Looking at the details, wondering why you shot so fast on a tripod! 1/320 when you have morning light and a tripod at your discposal seems a little hasty. Stopping down a bit would have increased your dof and slowing shutter should help result in much more rich colours, and possibly less shadows.
Still, you finished well and have a fave, nothing to complain about there! Good work. Just try to think of your tripod as something to hold your camera steady for slow work. Look forward to seeing more of your shots.
