Thanks the the asana looks beautiful. The forward bend and head lift looks a bit like exerted rather then natural flow. I am hoping this is performed after kurma mudra, which itself is done after the awareness of the kurma nadi ?
First is the awareness of the sphere of kurma - 'avarana' - Then is the mudra of kurma ( both for solar and lunar sides ) and finally the beautiful asana that you have shown. that would be more complete.
atleast that is what I have learnt from my preceptor. Hope that helps.
