Brilliant shot. Was it hand held, or were you steadying on the ground?
Using my phone, if you zoom right in the sharpest area is the right side curled part of the 2nd bud up, everything else is just starting to soften.
You still have lots of latitude to use a smaller apature to increase DOF. For me it needs that extra half inch. I think then it will have e that 3D look that makes it pop.
It's a great shot worthy of putting in the wall.
