Thanks for the comments. You're right about the compression on YouTube. It obliterates the detail in all but over-sharpened images, so in a work-in-progress image like this, it doesn't do it justice. In the finished hi-res image every pore and little hair is intact, but I always work WITHOUT input sharpening and then do output sharpening at the end of the workflow. I agree it looks plastic here. Might remove it. Might also consider Vimeo as an option – cheers!
