Hi!
I like this a lot!
Yoe've captured the communication part with the little waves in front. I see the body as the "world" latitude/longitude squeeked into crab shape body. :-)
I see the stilised legs as operating points connecting remote locations to crab body and communication services.
I even like the font!
Excellent!!
What i would like to elaborate is to find a more....masculine crab. Even if i do like your work very much the crab reminds me of something from a kids television show, cute and cuddly.
Blackcrab needs to appear strong and stable. We will not falter and nothing can get us out of balance. Our logo do not make people go:" oh, what a cute little crab". (Even if i personally think the crab is very cute...:-))
Thanks for your great work!
Good luck
