@domenicododaro Oh I do realize your photos use minimal processing and are beautiful on their own, but I mean your multiplicity shots, your scaling (like tiny you here), etc.!
@moreyoulessme well, no actually I use at least 3-5 pixel feather and the refine with a similar size eraser at hardness 0. The problem here was lighting and relative position. Though I paid a lot of attention, and took my selfportrait climbing on a stair in order to stay in the same position as the orchid flower, the difference in size (yes in real life I am a little bigger ;-)) matters! Besides, the bokeh of a 105 micro lens is quite different at 5cm than at 5 meters...
