tuning of light and shadows

So after couple of hovers I’ve came with this picture. On this one is a change in some details which were wrong in previous stage. At first I’ve though that shadows were not enough dark and secondly there were on wrong positions. So I’ve fixed the placing of them and then found out that a “Brilliant violet” is ideal color for darkening of dark brown tone, because i didn’t want to use a black color or any dark greys..
