I'm with you Ed. I like the two you do like, probably for other reasons - the stick figures whose selective edging I enjoy regardless how they are effected - being one.
As for the other two, the face is a must have photograph - gee, I must photograph this, it must be interesting - I suspect. The other, while I like negative space, and no rules work, does not click with me.
Beck's first toned piece I also like for some obtuse reason. The goth-horror element, the unusual color. Regardless, it makes me think. Skj.
