edit2: not really sure about Adlar, I just tried to change some little parts but I don't see anything wrong
I figured out what was bothering me. I've attached a comparison between yours and an edit I did on it to give an idea on how I think it should be fixed.
On yours, right above the hand, it is too dark, which is what made my eyes think that it went behind his head, yet it was obvious that the mustache was behind the staff, and that was what bothered me; it seemed that the depth was messed up on the staff, because how could it be behind his head but in front of his mustache?
In the edit, I "tried" to make the part above the hand more visible (I don't think I did a good job though). Also, I moved the top part of the staff over more, to look more like that actual picture. Anyway, I just made it to show you what was bothering me, but if no one else is bothered with it, then just ignore me; you're doing great work.
Btw, VERAN IS GRRRREAT! I like it.
EDIT:
For the Happy Mask Salesman, I think you need to flip the eyebrows around. But it still looks pretty good.
