#36 I like the concept but it looks too pointy, Looks better then #35. Not sure what #34 is supposed to represent. If #36 can be made to look not as pointy as it is (not sure how!) It is the closest to what we like of yours at the moment!
#48 #47 looks much better, need to increase the definition of these designs and match wording colour with logo colour somehow #46 smart but over the top
