Absolutely love both your entries. Couple of suggestions: 1) #15: You have two distinct shapes that fills the brain image. a C and a 3 shape. I see those actually as an smallcap "a" and an Uppercase "B"! It would be interesting to see that smallcap and uppercase being re-used in the company name as well - meaning you substitute the a of armored with that inverse "c" shape of the pattern in the brain, and you substitue the b of brain with the uppercase "B" shape of the pattern in the brain. Hope I make sense! 2) #14 It seems that you use an "a" in your logo. can you just use inverse that same symbol and alternate so that it looks like ab ab ab ab right through? as well as the central symbol - a on top - b just belo (currently the below reads like an "e"?)
