Bovo law and polar bear logos are tremendous on your portfolio. Talented.
#14 is a bold move and really inventive but a little phallic?
#15 and
#13 I like the arrow thing but the two of them doesn't work (yet?). Please explore fulcrum as balance point, arrow point, F in arrow point, all that.
Also, the cool factor of bovo and polar bear are part of their attraction. I would wear those on a t-shirt and I would not wear any of the logos submitted on my recent contest so far. You have that skill set.
Thank you and good luck!
Philip
