Nice work so far! Nice pose!
I do have to agree with spectr that the right hand is way too small.
Love the way you treated the jacket!!!
There are a few other areas that needs some tender loving care
the hat is a bit undersized... especially in the back.
the boots are way too small. How long are the boots? In 1/9 scale,
they need to be around 3.5cm 3.6cm. Hands and feet can be
slightly larger on miniature scale figures.
The legs are unusually long. I know some people have longer legs
than others. To me, it looks like as if you elongated the legs after
the basic armature was finished to achieve 20cm height.
Looking forward to seeing more progress pics!
