Definately getting there.Looking very good! I am doing this exact piece at the moment and haven't been on here in a few months..how cool is that!
Perhaps the left arm could use a bit more of a pronounced feather on where the light and shadow meet on the bottom part of the arm (shot 4 here on this page of your post)
Maybe after this hit the the highlights again for contrast...but....this is a work in progress and I am sure you know where you are going with all of this. The copper breastplate- love it!! I did an approach using Games workshop paints then went over the whole plate with oil washes...I'll keep an eye on your progress so keep these pics coming!! Great work thusfar!! Perhaps, I'll post some pics in a few months..I just haven't the patience to set up in progress pics, but certainly appreciate you doing so..helps seeing another approach. All the best, Steve
