The freehand actually looks quite delicate and clean, nice! The hair is well highlighted as well, just a bit too yellow for my taste. Same problem with the metallics, they really need some shading and you could take up the highlight on his face a notch. I also believe it would look better if you painted the gravel on the base.
There are some more pics on eBay I had to reduce them a bit so they went a little ........mmmmmmm. I can email originals then you can examine his finger nails
Enjoy
