Hi Magdalena. Needless to say how wonderful is your work :love: . I was looking at your work and the original piece, and here are a pair of comments 
In the original piece, the column (just behind his left arm) seems to be supporting a huge stress in trying to sustain such a pose.
I would say that the contracted muscles of the right leg should make it more thick than the left one.
I wonder what are you looking for in this work. Are you looking for a more dramatic result?
Best regards.
P.D. Looking forward to see those shots 




LOL


:buttrock:
but I enjoyed the process!.. I wanted to use mostly a square brush [but did use a bit of the regular roundish] and b&w on this
