D Akey : Thanks a lot my friend ! In fact I've tried to leave so areas unfinished several times ... I just can't, simply because for me every detail is part of the character and is important, every little scar, skin pore , wrinkles, etc.. has a story behind it and I just can't leave that behind.
Delofasht : Thank you very much ! I have to say it took me a while to figure out how I could get this result with ArtRage. I used to work with Photoshop and and the difference between these two softwares was a bit disturbing at first but I kept trying cause I knew I could do nice things with ArtRage.
