Robin Williams WIP Continued

Here's another update on my tribute portrait of Robin Wiliams.  I'm really trying to focus on realism with this one.  I'm still using Pentel P205 mechanical pencils with 4H, 2H, H, B, and 2B leads.  I'm blending using a q-tip cotton swab, a medium tortillion, soft bathroom tissue paper, and a hake brush.

I'm pretty much done with the head/face now I'm moving on to the sweater.  More to come soon!
