Interesting; I desire more white in the middle - really want it to pop - "distinctive" 
Consider playing around with other designs - I want to view a vintage sperm whale in middle of crest / circle - "white sperm whale".   Similar if you walked down a pier, just saw a metal design coming from roof of house, pub, establishment - sperm whale outline / design.  "Moby Dick" book sperm whales.  
I'd strongly consider a Sperm Whale as part of my logo ... one way to do it.  Sperm Whale on Crest / Shield or circle.  Then one or three nautical rods w/ flags coming up from top of crest.  Wazy Nautical flags.  First one - Senior. 2 Wazy flag - port 3. Network.  Or three even (not wazy) nautical flags - see on sailing boats.
Speed typing, between tasks, love your creativity; thank you so much! 
Visualize - I want the middle part to pop - likely has to be color white - reason I like current 
#1 entry - white inside design pops ... "distinctive" 
Thank you so much.
