Kudos on the new designs, especially
#23. It's a very distinctive design, and would do quite well for brand recognition! The only thing about that one is I'm trying to decide if I like the happy feet or not. Could you do it without the feet?
I like
#29 &
#30 as well, but think a) the design does look better with the bolder font, and 2) you can't really tell what the magnifying glass is -- you can kind of see the "reflection" if you will, but I think the "searching" that you were trying to convey got a little lost.
I like the italic font used on entries
#25 through
#30. However, after seeing the larger "roof line" on
#23,
#24,
#29 &
#30, I think the smaller roof line on the other designs is too small.
#26,
#27,
#28 &
#31 now just seem a little too blah.
