Thanks for your comment.
It is a single shot with minor adjustment in PS. Haven't used HDR for many years.
I was surprised when I first saw this picture as it looked like Chinese painting which usually inspires me. I've found out, on occasion, I got the pictures similar to this one (dream-like) with long exposure.
To be honest, I really like this picture as it is different from my usual works, as you said it's lifeless and unreal. That maybe the reason why I like it
