#12 is very striking and has a deceptive simplicity that i really like -- esp the openness and the arm/hand-like qualities of the menorah branches. typeface is a little too casual but stylistically similar to what we're going for.
#19 probably has too many symbols at odds -- but i like the synergy. we hadn't previous considered a shofar in the design, so i like seeing options with one. after all, we're making a pretty major announcement with our rebranding.
though the others aren't *quite* right, there's a lot of talent and creativity here! nice work!
