the "bokeh" is not CA. its actually the waterfall at the background.
the lenght of the model's arm looks long cos it is my fault on not framing her correctly. The perspective in which i shot was from a waist level and she was rested on a chair leaning slightly to her right thus elongating the arm. The punchy look u talk about i guess i didnt achieve as well cos i was at close range and should have stood further back and shoot with telephoto with small aperature. (correct me if im wrong ya? =) )
I was going for the de sat look. Not that much into big vibrant colours at the time being unless its like pastel and all.
Hope i explained my technicalities correctly. =) thanks for the feedback again.
