Great painting!
As you said we could comment although you are done, I'll do it:
Maybe it is just me, but I can't recognize a clear area of focus, I think the the face, the right arm and the earth symbol are compiting for attention. The face is always a focal point by default, but in this case is not strong enough as it is les contrasty and into the distace, and horn beeing contrasty despite it it is at the same distance than the face makes it a little bit inconsistent. The right hand shoulf not be a focal point by defaul, but as it is very contrasty (with the background) it calls for atention as well, and the earth symbol is the brightest and sharpest point in the image, so it calls for atention as well. So I think you should play with this factors to decide only one clear focal point and push the others to a second read.
I hope this helps.
