If you're interested in feedback:
That's a great logo, but my eye keeps getting caught on a detail: The shark's dorsal fin lays directly atop a diamond facet, and it's right in that uncanney valley. It's close enough to the facet that you really don't even see the facet beneath, but it's different enough that the matching mirror image on the other side of the diamond obviously doesn't match up. The asymmetry jars my eye in a way that, for example, the uneven rays coming off the ComStar logo do not. That fin-facet relationship feels like it needs to be altered. I kind of like the idea of making the fin a more perfect mirror image to the opposite facet. If the asymmetery were instead the left facet being overlaid by the shark's body with the right facet blending into the body/being the fin, I think that'd be pretty neat.
