Clean lines and good coverage, I'll give you a 6 for that. The eyes are pretty good, but not fabulous.
I don't know where the 10 comes from either. It's fine for a painter 2-4 years into painting, but it's almost insulting to the real masters to give this a 10.
Again with the 10s. good color choices but again minimal shading, especially on the axes. Looks like little detail on the axe handles. Nice details on the face, but the skin looks like 1 shade with no shadows or highlights.
