Logo Design

I have been working on my 1st freelance project which is a logo design. The logo is for a software program that works as an installer for OpenBSD (the program was tentatively called "sshabang"). A friend of mine is in charge of the software updates and was looking for a new logo. So I started coming up with some preliminary sketches that incorporated aspects of the OpenBSD blow fish. The OpenBSD blowfish logo is copyrighted by OpenBSD.

The best 2 ideas were a bomb with spikes, and a series of cogs that morphed into the fish. I was thinking of "Spy vs. Spy" when I drew the bomb, and then added spikes to mimic the fish, and just make it look menacing. However, it was mistaken for a stick of dynamite in the fish's butt, so I guess I didn't convey the look I was going for. My friend preferred the cog logo, so I went to work in Illustrator and came up with 3 designs (all basically the same). The design is not finalized yet, and I think I need to work on some aspects (like the tail). Once I get some feedback I will be sure to post updates.
